The Clinic

Cara calls Captain Hanson to report Tom’s murder. Hanson explains that he cannot reach the Clinic until the following morning due to weather. He suggests that the Clinic staff consolidate everyone into a single dorm for safety.

Jade and Dex enter as Sierra reveals to Madeline that Meg is Haley’s sister. The other patients are furious at Meg for continuing to lie to them, and Meg is devastated by their disappointment. Madeline also accuses Meg of stealing drugs. Meanwhile, Meg panics as the Clinic’s lobby is locked down, barring the exits.

Devastated, Meg calls Harry to tell him that she is coming home. She briefly wonders if he has been sending her the texts from Haley but then decides against it. Harry reveals that Sierra was committed to a psychiatric hospital 10 years prior.

Harry explains that Sierra was hospitalized to treat her intrusive thoughts. Meg shares her theory that Haley is alive and being held in the Clinic against her will. She lies to Harry, agreeing to come home, and then has a powerful hallucination of the woman in vintage lingerie saying that Harry can’t be trusted.

Meg scales the Clinic’s walls and breaks into the treatment room via a skylight, nearly dying in the process. She is devastated to find that Haley is not in the treatment room. As a hallucination of the woman in vintage lingerie mocks her, Lutz enters, claiming to know her true identity.

Lutz implies that he plans to keep Meg at the Clinic against his will. When Meg calls him a “psychopath,” he agrees, explaining that he diagnosed himself while in India. He claims that psychopathy is unfairly stigmatized and that Meg is the same as him.

Max and Cara speculate on why someone might have killed Tom. Max argues that Tom was lured into Max’s office by a woman, possibly Madeline. He suggests that they not tell Lutz about Tom’s death. However, when the security system resets, Cara realizes that he already knows.

Lutz reveals that a panel of experts has diagnosed Meg with “sociopathy,” more commonly known as antisocial personality disorder. Meg denies it, but his description of the disorder resonates with her. Lutz insists on another treatment, and Meg agrees, hoping he is bluffing.

During the fugu treatment, Meg reveals that the house from her memories was the house next door and that she saw Haley lying nearly lifeless after her encounter with Mr. Priest in the bedroom. Lutz injects more fugu. As she remembers playing cards with Mr. Priest, her body goes into shock.

When the security system rejects his attempts to log in, Max realizes that Lutz has shut down the system. All patients are redirected to cryotherapy. Max suspects that Lutz is trying to kill the patients to disguise his use of fugu, which dies in cold temperatures.

During a hallucination featuring Max, Meg realizes that the woman in vintage lingerie was actually an illustration on Mr. Priest’s playing cards. She reveals that Priest taught her to play poker and that she feels like she’s lost everything.

Meg wakes alone in the treatment room. She sees Mr. Priest enter the lobby on a security camera and watches in panic as he approaches the treatment room. She dislocates her shoulder to free herself, but he manages to corner her and addresses her by name.

Mr. Priest asks Meg if she remembers coming to his house with Haley and learning poker. He apologizes for using inappropriate playing cards but explains that he needed to keep her distracted. When Meg looks confused, he reveals that Haley found their mother after a suicide attempt.

Meg realizes that her memories of Haley and Mr. Priest in the bathroom are actually from the day of her mother’s attempted suicide and that Haley and Mr. Priest were trying to protect her. Priest explains that Haley tried to protect Meg even after Haley left home as a teenager. Meg vows to find Haley’s killer.

Max argues that Dr. Lutz doesn’t value human lives and that he would risk the lives of the patients in order to save himself. Cara suggests that Max cut off power to reboot the system, granting them access. After Max leaves, Cara is confronted by Lutz. She formulates a plan.

Meg calls Harry to tell him that she loves him. She then meets the other patients in the cryotherapy room and apologizes for lying, finally admitting to herself and them that she has addictions. As she says goodbye, she realizes that someone from her past is in the group. She leaves, knowing that she is followed.

Stalling for time, Cara offers to team up with Dr. Lutz in his goal to sell the fugu drug to human traffickers. Lutz insists that he has a different plan for drugs. Before he can reveal it, he receives a call and makes plans to leave the Clinic with Cara.

Meg goes to the medication room, where she is powerfully tempted to take an oxycodone pill to protect her from what she knows is coming. She decides against it as Jade enters. Meg realizes that her instincts were right the entire time.

Meg realizes that Jade is her sister Haley in disguise. Haley admits to leaving the notes and attacking Meg throughout the hospital in order to dissuade her from investigating. Haley teases Meg for not recognizing her immediately.

Haley reveals that Dr. Lutz is developing a procedure to help people fake their deaths using fugu and start new lives. She shows off her plastic surgery, explaining that she plans to start a career as an actress. She warns Meg that Lutz will not let her live unless she joins them.

Lutz reveals that he plans to charge $10 million to fake clients’ deaths and provide them with new physical appearances. He claims to have seven clients ready to go once Haley/Jade is fully healed. Cara sees security camera footage of Max being held at gunpoint. Lutz aims a gun at her, threatening to kill them both.

Lutz leads Cara to the cryotherapy chamber, with Max and the patients waiting inside. Lutz pushes her in at gunpoint. Max indicates that he has a plan and lies to the patients to explain his and Cara’s presence at what he describes as a therapy session. Lutz locks them in, and the room begins to cool.

Haley explains that their mother deliberately drove a wedge between them and that Haley never wanted to leave. She asks Meg to join her and Lutz and to start a new life with her. Meg rejects her, explaining that she cares about the other patients and needs to help them. She has a withdrawal-related seizure, but Haley refuses to help.

Meg wakes tied to a bench in the medicine room. Lutz demands that she submit to surgery, insisting that her personality suits his needs. He reveals that Haley killed Tom when he recognized her and threatened to expose her. As Lutz speaks, Haley disassociates.

Max tells Cara that the cryotherapy room will power down after five minutes, regardless of what Lutz programs. The group struggles through the five minutes, with Sierra and Dez nearly dying of hypothermia. As the clock hits five minutes, the power is cut, locking them inside.

Haley cuts a wire to stop power to the spa. Lutz reveals that he intentionally chose a cryotherapy chamber that would automatically lock if the power was cut. He tells Haley to kill Meg. Meg insists that she won’t do it, but Haley doesn’t stop Lutz from approaching Meg with the live end of the cut wire.

Cara realizes that although the cryotherapy room is no longer producing cold air, the insulation will keep it cold for hours. At Cara’s urging, Max encourages the patients and helps them to keep warm. As he fails to find an escape, Cara fears that they will die.

Lutz presses the live wire against Cara’s chest, triggering heart palpitations. He explains that her death will look like a heart attack, common in detox. Meg begs Haley to help her, reminding her that her new name, Jade, was the name of a television princess the girls idolized as children. Haley grabs the live wire and then touches Lutz, electrocuting them both.

The power surges back on, allowing the patients to escape. As they attempt to warm themselves and recover, Meg appears to guide them out of the Clinic. Meg warns Cara not to let her feelings for Max cloud the fact that he aligned himself with criminals to secure a patent that would make him famous. Harry appears at the Clinic, and Meg kisses him.

Harry explains that he had already flown to the Pacific Northwest when he last spoke to Meg. She asks him to take her home and for help with the rest of the patients. Captain Hanson and Officer Meyer appear and joke that they seem to have missed the party.

A month later, Meg attends her first session with a new therapist, who explains that antisocial personality disorder is a spectrum and that Meg is in charge of how she sees the world. They work together on identifying her emotions and impulses. He reminds her that her childhood trauma had a deep impact on her personality development.

Investors buy the Clinic after Dr. Lutz’s death and hire Cara to run it. Hanson and Meyer report that Lutz’s death was ruled an accident and that Max was arrested for smuggling fugu. Cara admits to them that she will overcharge insurers to provide better treatment for patients. She does not reveal that she kept a small stash of fugu and is developing her own secret treatment.

It is revealed that Haley survived the electrocution by standing on plastic, which grounded her, preventing the electricity from harming her. She convinced Lutz’s criminal connections to help her forge a new identity as an actress from Iowa. Haley and Meg’s relationship remains distant. Harry asks Meg to marry him, and she accepts.
