The women realize too late that they are lost, and there is a disagreement over whether they should retrace their steps or use a nearby creek to re-orient themselves on the map and find the camp. Bickering breaks out. Beth loses their fuel canister while searching for her cigarettes, and the group sends her to look for it. Morale is very low.

Beth is outside smoking when Aaron and Carmen leave the hospital. They stop to speak with her and ask about her relationship with Alice. Beth admits that Alice was combative and disrespectful with many people, but especially with her. She knows that Alice judged her for having been incarcerated; while Beth was still actively battling addiction a few years ago, she had stolen from Bree and punched her in the face when confronted. Aaron and Carmen ask Beth’s opinion about what happened to Alice, and Beth tells them that Alice likely attempted to return to headquarters alone. Alice had threatened to do that multiple times and seemed in a sour mood after a heated conversation with Daniel. Now, Beth asks if Alice was “up to” anything; Alice had recently begun requesting more and more confidential files from the archives, and this behavior strikes Beth as suspicious.

During the hike, Alice angrily insists that Beth retrieve the canister from the riverbank, but the bank is steep, and Beth is too afraid to scale it. Lauren volunteers but falls into the water and hits her head on a log. The other women are able to rescue her. When Lauren regains consciousness, she wants to stay near the river until she feels better, but Alice insists that they press on and try to find their next camp.

Aaron and Carmen speculate about Alice, Beth, and Bree. They wonder if Beth has shared her suspicions about Alice’s document requests with her sister. They also believe that while Beth might not have cared too much about what happened to the company, Bree would have. They notice that Daniel’s car is gone and learn from Jill that he left to attend to “family matters.” Jill declines to provide further detail but testily asserts that whatever called Daniel away must have been important. 

They ask about the company, and Jill notes that everyone in her family, with the exception of her children, works there even if they don’t want to. She tells them that employees were selected for participation in the retreat based on upper management’s perception of which ones needed some additional character-building. Lauren had been making mistakes at work, while Beth was “not corporate” enough, and Alice had been named in several complaints. Bree was chosen because she was slated for a promotion. When the investigators ask Jill about the bruise on her face, she reluctantly admits that on the last night, their arguments boiled over into a physical fight.

On the hike, Alice has the compass and navigates the route as the women try to find their campsite. Meanwhile, Jill reflects on her work at the company. Her father and brother are engaged in illicit financial activity and always have been. When Jill found out about this, she tried to quit but was sucked back in by her sense of familial obligation. She had been the one to hire Alice and did not regret the decision because Alice is a good worker. However, Alice is also a difficult person who is widely disliked. At the end of the day, the women realize that Alice has been leading them in the wrong direction.

Aaron looks through his files, hoping that his investigation has not led to Alice’s disappearance or death. When his eyes begin to blur, he heads outside to the trailhead to get some air. He runs into Lauren, who explains that she was out looking for Alice. He asks her about the physical fight that took place during the hike, and she explains that everyone was involved in the altercation, even Jill. He contemplates this new information and heads back to the lodge, where he encounters Beth. She confirms Jill’s statement and adds that no one got along with Alice on the trip, before or after they got lost.

The women argue about what to do. Because they have no idea how to find the campsite now, they stay where they are for the night. They continue to bicker, and the argument heats up when someone’s uneaten lunch is discovered. They had previously agreed to pool their remaining food, and it now appears that one of the women has been holding back supplies for herself. Alice immediately accuses Beth, who heatedly denies that the food is hers. Bree admits to not having eaten her lunch, but Alice doesn’t believe her and accuses her of lying to protect Beth. Beth realizes that Bree, who has disordered eating patterns, likely refrained from eating her lunch on purpose, so she takes the blame. Everyone believes Beth’s story, and Beth notes that the group’s “natural order” is restored.

Carmen pulls Aaron aside and shows him photographs of the women whom Kovac has killed, noting their resemblance to Alice. Aaron isn’t so sure that Kovac’s son is responsible for Alice’s disappearance, but he mulls over the prospect in his mind.

The weather has taken a turn for the worse, and the women struggle against the icy wind and rain as they silently march onwards. They are all tired, hungry, and thirsty. Beth and Bree bicker, and Beth tells Bree to watch out for Alice. Bree snaps back that she cares about her career and that Alice can help her to advance in the company. She recalls her decision to have an abortion so that she would not lose the opportunity to work at Bailey Tennant and reflects that she feels just as dedicated to her job now as she did back then. Alice then castigates Beth for smoking and throws her cigarettes into the bush. Jill rebukes Alice. Beth goes to retrieve the pack and calls to the rest of the women that she has found something.

King tells Aaron that the search will have to be scaled back if they do not locate Alice soon. Someone has leaked details about the cabin to the press, and the public is buzzing with the knowledge that Kovac may have used the building during his own time in the bush. Aaron and Carmen return to Melbourne, hoping to visit Alice’s home to look for the documents that their supervisor still wants them to obtain. They also plan to visit Daniel’s home. When they drive past Alice’s house, Daniel is hastily leaving. Puzzled, the two investigators realize that there is still much about this case that they do not know.

On the hike, Beth has found a small, dilapidated cabin. It does not appear to have been used recently, and it is warmer inside. However, there is a mattress with a large, dark stain that fills them all with dread. Alice argues that they should leave immediately and keep walking, but everyone else wants to stay for the night. Jill decides that the group will stay, then loses her temper when Alice objects again. Alice tells her that in the morning, she plans to walk out alone. Although Jill tells her not to, it is obvious to everyone that Alice plans to go anyway.

Aaron looks up at Alice’s house and sees the momentary flash of a face in one of the windows. At first, he is sure that it is Alice, but he realizes that it must be her daughter, Margot. They talk to Margot and ask her about Daniel. Margot explains that Daniel’s son, Joel, is her ex-boyfriend and posted explicit photos of her online just a few days ago. Margot is sure that Daniel came to discuss that situation, but she didn’t open the door. She is supposed to be with her father, but she is too mortified over the photos to face him. Aaron and Carmen arrange for Margot to temporarily stay with Lauren and Lauren’s daughter, Rebecca.

The weather begins to clear. The women walk outside, and Beth stumbles over what turns out to be the shallow grave of a dog. It is marked with a wooden cross that bears the carved name of “Butch.” The women are unsettled, and Alice asks about the name of Martin Kovac’s dog. She recalls he had a dog that he used to lure in hikers. The others accuse her of attempting to use fearmongering as a way to manipulate them into leaving. Jill and Alice get into a heated argument, and it is eventually decided that the group will stay the night at the cabin. Jill reasons that exposure is more of a threat than ghosts.

Aaron and Carmen bring Margot to Lauren’s home and are surprised at the tidiness of the house. Margot tells them that Rebecca stopped going to school six months ago because she was being bullied. Students teased Rebecca about her weight and shared photos of her eating lunch and undressing after gym class. Now, Aaron and Carmen are shocked by Rebecca’s appearance. She is skeletally thin, and Aaron initially wonders if she has cancer, then realizes that she has disordered eating patterns. Rebecca is at working making friendship bracelets, and Lauren explains that this is a mindfulness task that her therapist advised in order to help her combat anxiety. Lauren guiltily looks down at her own wrist; Rebecca gave her one of these bracelets, but she lost it during the hike.

On the hike, Lauren gets a fire lit, and the women gather around it. Alice asks Lauren about her daughter, Rebecca, and Lauren thinks to herself that Alice really should have reached out on this topic months ago. Bree directs their attention to the stars, and they are momentarily awestruck by the sight. They discuss fate and free will. Alice is sure that everyone is in control of their own destiny, but the others are open to the idea that life might be “written” in the stars. Jokingly, Beth notes that she and Bree, as twins, were born only moments apart and are as different as can be. The women worry that they will not be rescued, and Bree in particular grows anxious about the prospect of dying alone in the bush.

Aaron and Carmen leave Lauren’s house and head to Daniel Bailey’s large, opulent property. Daniel’s son, Joel, is missing, and both Daniel and his wife are worried. They claim that Joel did not publish explicit photos of Margot online, saying instead that Margot had sent the photo to Joel unsolicited. Daniel explains that they’d purchased a new tablet which was somehow synced to Joel’s phone. His wife found the photos while setting up the tablet and had gotten upset. Because Joel had several friends over when she found the photos, Daniel theorizes that one of them put the images online. He adds that this situation happened just prior to the start of the retreat and is the reason he was late. He refers to a heated conversation that multiple people reported seeing between him and Alice and states that he had been explaining what had happened to Lauren. Aaron comments that because Joel is 18 and Margot is not, the family will need a good lawyer; Joel has distributed pornographic images of a minor.

Bree catches Alice trying to call Margot behind the cabin. Alice tells her that there was no signal, but Bree reminds her that each attempted call will drain the phone’s battery.
