Plot Summary

Five years after her son, Sam Crowley, vanished on his 21st birthday, Dr. Rowena “Ro” Crowley returns to Carralon Ridge, the rural Australian town where she formerly lived with her family, for the anniversary. The town is a hollow shell of its former self, as its residents and businesses have been steadily bought out by the encroaching Lentzer coal mine.

Ro, a doctor who now practices in Sydney, reunites with her estranged husband, Griffith “Griff” Crowley, and their 23-year-old daughter, Della Crowley, at the family home. Griff now rents the house from the mining company and works as their community fire safety officer, while Della is an accountant in Sydney. Shortly after Ro arrives, Griff tells her that the company is terminating his contract and that he will have to leave the house and, most likely, Carralon Ridge.

Five years ago, Sam, who was studying rural decline in college and had come home to interview the locals, disappeared. His rental car was found parked near the track leading to three abandoned properties: the Hillary farmhouse, formerly owned by Griff’s cousin Warren Hillary, who died by suicide three years before Sam’s disappearance; the ivy cottage, once home to Ann-Marie Birstock and her son Jacob Birstock; and the stone bungalow, which belonged to Bernie Reece. Sam’s laptop and a notebook filled with interview notes were left in the car, but they offer few clues as to his fate.

The fragile reunion of Ro, Griff, and Della is fraught with tension and grief. While visiting the abandoned houses, as has become their yearly tradition, Ro and Griff encounter Ann-Marie trespassing at her old cottage, a habit that worries Griff. At the Hillary farmhouse, they find that high winds have brought down large branches, smashing part of the back verandah. Ro remembers how Sam’s footprints were found tracing a path through all three houses, but they never knew why.

The next day, Ro and Della visit Ro’s friend Heather Reece and her husband, Noel Reece, at their house. While Della evasively goes to talk with Darcy Reece, Heather and Noel’s son and a close friend of Sam’s, Heather shows Ro to the “Last Chance Saloon,” the Reeces’ outbuilding that has been built and decorated with salvaged town relics. Later, Della reveals what she has learned from an old schoolmate: Years ago, Darcy had a drunken argument with his then-girlfriend, and Jacob, the third in their friend trio, said that Darcy should feel guilty because he “did something stupid and then […] Warren killed himself” (151). When Della has tried to question Jacob and Darcy about this, they became evasive.

The mystery deepens when Ro and Griff, while clearing out their shed, find four of Warren’s father’s old running medals in a box of Sam’s belongings. The medals were always hanging in Warren’s study, and while they don’t believe that Sam would’ve stolen them, they don’t know how else they would’ve gotten in the box. Then, while clearing the damaged porch at Warren’s house, they find dark stains on the hidden edges of the floorboards—old blood—and discover a key that was lodged between the planks before the blood soaked in. The discovery of the blood and key provides the first potential clues about Sam’s disappearance.

The key fits no locks at the three houses or in the dying town, and a call to Sylvie Hillary, the local pub owner and Warren’s ex-partner, goes unanswered. Ro’s long-held suspicions about Sylvie, fueled by a cryptic question mark next to Sylvie’s name in Sam’s research notebook, drive her to confront the pub owner upon her return.

Under pressure, Sylvie finally confesses the secret she has kept for eight years: On the night he died, Warren called her. She had been living above the pub, separated from Warren over his refusal to sell the house and move with her to be nearer to her ailing mother. He told her that he was going to sell the house to the mine after realizing that she was more important to him. Furious and hurt by the delay, Sylvie rejected him, something she has regretted since his death. She reveals that Sam had somehow learned of this conversation and questioned her about it the day before he vanished, but she denied it, not wanting to tarnish Warren’s memory with the locals. This new information re-frames Warren’s death, and Ro realizes that Sam was on the trail of a secret.

Later that day, Jacob approaches Ro and says he’s ready to talk. He confesses to Ro, Griff, and Warren’s brother Damien that he, Darcy, and Sam used to play pranks when they were teenagers, including on Warren. They’re the ones who took his father’s medals, which they felt guilty about after Warren’s death. Damien comforts Jacob by confiding that he, Warren, and Griff also played pranks when they were young; he also mentions that Warren used to make small, hidden carvings of a face with a “W” for a mouth all around the town, including at his own house. This causes Griff to realize that Sam wasn’t at the three houses for his thesis; he was searching for these carvings, likely to assuage his guilt over the pranks. As Ro and Griff trace Sam’s last known path through the houses, they find the carvings, confirming the theory.

On the anniversary of Sam’s disappearance, and what would have been his 26th birthday, Ro, Griff, and Della make a birthday cake in remembrance. As Ro stares at the flickering candles, she feels a vague but important thought or memory form before it disperses. Later, the family goes to a public memorial for Sam, where Darcy unexpectedly criticizes the town’s fixation on the past. After the memorial, as Ro and Griff stand alone in the spot where Sam’s car was abandoned, Ro’s memory from earlier returns. She realizes, based on Darcy’s comment about people being stuck in Carralon Ridge, that the key they found on Warren’s porch is for the Last Chance Saloon, the door of which was taken from Bernie’s old stone bungalow. She and Griff rush to the saloon, and the key fits the lock.

A distraught Bernie confesses the truth about Warren’s death. Eight years ago, he came unannounced to visit Warren and overheard him on the phone with Sylvie, agreeing to sell. Enraged because Warren’s sale would devalue his own home and force him out, Bernie confronted Warren on his porch. Bernie’s son Noel was also present. During the argument, Bernie struck Warren, who fell and hit his head on the outdoor table, dying instantly. To protect his ailing father from prison, Noel staged the death as a suicide, taking Warren’s body and truck to the mine quarry.

As the family absorbs this horror, Griff’s focus narrows. He confronts Noel, noting that he stopped working on the saloon about five years ago, around when Sam disappeared, and wondering if it might be because of guilt. Noel, overcome with guilt, confesses the second, more destructive secret.

On the day he disappeared, Sam visited the saloon. During their conversation, Sam, piecing together information, confronted Noel about his knowledge of Warren’s plan to sell. Panicked that Sam was on the verge of uncovering the truth, Noel struck him, killing him. Noel buried Sam’s body under the floorboards in a corner of the saloon.

In the aftermath, Noel calls the police and confesses to both killings. As authorities descend on Carralon, Ro, Griff, and Della retreat to the ridge overlooking the town, watching the community they once knew become a crime scene. From a distance, they observe their friends, like Sylvie, Damien, and Ann-Marie, gathering in shock. Darcy leaves an envelope for Ro outside their house, containing a note of deep sorrow and a photograph of a smiling Sam, taken by Darcy’s drone during his final visit. The image provides Ro with a measure of peace, confirming that in his last days, her son was happy.

One year later, Carralon Ridge is completely abandoned, and the three houses have been demolished. The former residents have scattered, forging new lives elsewhere. Ann-Marie works for the Royal Flying Doctor Service, while Sylvie, Jacob, and Darcy have relocated to nearby Blenheim. Damien, long suspected of being Jacob’s biological father, now visits Jacob regularly, investing in his and Darcy’s new business. Ro and Griff have reconciled and bought a house in a new country town. Together with Della, they find a new beginning. They scatter Sam’s ashes in the paddock of their new home, finally allowing him, and themselves, to be at peace.
