In the sun-kissed San Fernando Valley, a spirited teenager named October "Tobe" embarks on an impromptu stroll with her younger brother, Lonnie. The following day, Tobe sets off with her friends for a blissful day at the beach, but an unexpected stop at a gas station introduces her to Harlan, a charming young man exuding a folksy cowboy allure. When Tobe invites Harlan to join their beach outing, the subsequent consequences unfold dramatically, marking the beginning of tumultuous events.
As destiny would have it, Tobe and Harlan quickly find themselves in a romantic entanglement, culminating in a night of passion at Harlan's place. He takes her out on a genuine date, and the trio shares a pleasant meal before winding up at a lively party filled with dancing and drugs. The day after, Tobe returns home late, triggering a furious reaction from her father, Wade, who leaves destruction in his wake as he lashes out.
Despite Wade's escalating anger, Tobe continues to see Harlan, pushing the limits of her father's patience. Wade's rage eventually erupts again, resulting in a shattered bedroom window. As tensions rise, Tobe and Harlan embark on a horseback ride with a horse supposedly owned by Harlan's acquaintance, Charlie. However, upon their return, Charlie insists that Harlan is a stranger and that the horse was stolen, putting them at risk of legal repercussions.
When Wade arrives at the police station to retrieve Tobe, he discovers her resolute decision to end things with Harlan. However, Harlan, undeterred, takes Lonnie on an unauthorized shooting excursion, prompting a confrontation with Wade, who aims a gun at Harlan and demands he stay away from his children.
As Harlan's mental stability begins to waver, his erratic actions grow alarming. A chaotic scene unfolds at a nearby synagogue before he intrudes on his father's space—a Hasidic Jew who hides his own secrets. In a moment filled with desperation, Harlan steals sacred artifacts and childhood photographs. Later, he breaks into Tobe's home, hoping to convince her to escape with him. Initially thrilled by his return, Tobe's excitement quickly diminishes as she recognizes his deteriorating mental state. Their escalating argument culminates in a shocking moment when Harlan shoots Tobe in the stomach.
In the aftermath of the tragedy, Wade rushes Tobe to the hospital, where she is placed on life support. Meanwhile, Harlan attempts to erase his tracks by faking a 911 call and hiding away. He even deceives Lonnie into believing that Wade is to blame for Tobe's condition and portrays himself as the savior.
As the layers of truth begin to unfurl, Tobe regains consciousness only to find that Harlan has taken her son away. A tense showdown at a makeshift campsite pits Harlan against Wade, Charlie, and Detective Sheridan. The chaos escalates as Harlan kills Charlie and flees with Lonnie. Their escape leads them to an active film set, where the chaos continues to unfold. Wade and Sheridan soon arrive, seeking to regain control of the situation. In a desperate struggle, Harlan shoots Detective Sheridan and another officer.
As the climax approaches, Harlan and Lonnie find refuge at a nearby construction site, where Wade ultimately confronts them. In a heart-rending end, Wade delivers the fatal blow to Harlan, quelling the threat of violence he posed and leaving Lonnie forever scarred by the loss of his father figure.
As Wade drives Tobe and Lonnie towards a location steeped in nostalgia—the very place where Tobe and Harlan once enjoyed a sunlit day of happiness—Tobe clutches a small, meaningful box containing the ashes of her late brother, Harlan. Approaching their destination, she reflects, and Lonnie silently inquires how one can capture the essence of such a lost soul. In a touching expression of grief, Tobe responds softly, urging them to simply “think it,” allowing their memories to emerge freely, untethered by words. With reverence, she opens the box, letting the ashes dance in the wind, carrying with them the tender remnants of treasured memories and bittersweet goodbyes.
