Architect and devoted family man Evan Webber (Keanu Reeves) finds himself alone at home with his loyal dog, Monkey, on Father’s Day weekend. While his wife Karen (Ignacia Allamand) and their children enjoy a beach getaway, Evan is tied up with work and recovering from a shoulder injury. He is also responsible for overseeing the moving of Karen’s artwork, which is scheduled for an exhibit at an art gallery, under the watchful eyes of their assistant Louis (Aaron Burns).
During a heavy rainstorm, two women, Genesis (Lorenza Izzo) and Bel (Ana De Armas), knock on his door seeking directions to a party as their phone is malfunctioning. Being the kind-hearted man he is, Evan invites them in to dry off and use his Internet to locate the party. After realizing it’s located in another neighborhood, he kindly offers to arrange an Uber for them, though they have to wait about 45 minutes. To help them feel comfortable, he provides robes for them to wear while he puts their clothes in the dryer.
As they chat, the atmosphere becomes increasingly flirtatious, with the women expressing admiration for Evan’s wife and joking about Bel’s notions on polygamy and threesomes. The playful banter escalates, and before long, Evan finds himself unable to resist their advances, leading to an unexpected and compromising encounter.
The following morning, the reality of the situation hits him hard when he discovers that the pair has vandalized his wife’s sculpture. When he threatens to call the police, they insist they are underage, and a confrontation arises. Entering the scene is Vivian (Colleen Camp), a friend of Karen’s and a massage therapist who had intended to help relieve Evan’s shoulder pain for their appointment. Upon seeing the women, she storms out, leading Evan to a desperately chaotic standoff.
Evan attempts to tidy up the chaos left by the girls, but just as he is making progress on his work, he hears a crash. In an unfortunate sequence of events, Genesis knocks him unconscious using one of his wife’s sculptures. As he regains consciousness, the girls unpredictably confront him, initiating a horrifying game of dominance where they threaten to expose his infidelities and tie him up. The cruel twist solidifies when Evan realizes the sadistic nature of these women, who have turned his life into their personal playground of torment.
Louis unexpectedly arrives to retrieve the sculpture but falls victim to the girls’ antics and ultimately suffers a dire fate. The facade crumbles as the girls’ true intentions become apparent, revealing their history of victimizing men in similar situations. Their machinations lead to Evan being buried alive, a cruel “game” designed purely for their amusement. They film the chaos and upload it to social media, further escalating their sordid entertainment.
In a dark twist of fate, as they leave with Monkey, Evan is left to face the ruin of his life while the chilling realization of their actions sinks in. The scene closes as his family returns, unwitting of the horrors that have transpired. The narrative leaves open an alternate ending where Evan seeks vengeance, using Monkey’s GPS to locate the girls at their next target, a setup that hints at a grim reckoning ahead.

Unravel the ending of Knock Knock (2015) with our detailed explanation. Understand the final scenes, character fates, and unresolved questions.
In the original theatrical ending of “Knock Knock,” Evan’s tormentors, Bel and Genesis, leave him buried up to his neck after tormenting him in a twisted game, posting a sex tape, and setting him up to be found by his wife. This ending emphasizes a dark, nihilistic tone where the villains appear to triumph, and Evan is left to face the consequences of his actions. However, the alternate ending provides a different kind of closure. It shows Bel and Genesis leaving Evan’s house and stealing his dog, Monkey. Evan, using a tracking device, finds them, and in a full-circle moment, he confronts them by knocking on their door, echoing the film’s beginning. This version hints at a cycle of violence, suggesting that both the women and Evan are not entirely innocent and may have experienced trauma that drove them to these extremes. The alternate ending leaves open the possibility that Bel and Genesis are seeking revenge or justice for past abuse, hinting that their actions stem from deep-seated trauma rather than mindless cruelty. It also implies that the story could expand into exploring their backstories and motives, possibly setting up a sequel. While the theatrical ending is more nihilistic and fitting with the film’s darkly comedic tone, the alternate ending offers a more nuanced perspective, emphasizing themes of victims, survivors, and the cyclical nature of violence. Ultimately, the choice of ending influences how viewers interpret the characters’ motives and the story’s message about trauma and retribution.

In the quiet, cobblestone‑strewn town of Saint‑Maurice, the rhythm of daily life is punctuated by the chatter of market stalls and the lingering scent of pine from the surrounding forest. The community is tight‑knit, its residents accustomed to the familiar faces of a long‑standing doctor who knows every family by name. Into this gentle rhythm steps Knock, a man returning from a shadowy past he has tried to leave behind. He arrives with a polished new clinic, a crisp white coat, and a promise of modern care that seems both hopeful and oddly out of step with the town’s slow pace.
Beneath the veneer of his respectable new role, Knock harbors a pragmatic ambition that borders on the audacious. He plans to leverage his medical expertise not just to help but to profit, subtly reshaping perceptions of health and illness among the locals. The town’s trusting nature makes his scheme both plausible and unsettling, creating a tension between the earnest desire for wellness and the quiet manipulation of fear. As he moves through the streets, his charisma draws attention, and the line between genuine concern and calculated enterprise begins to blur.
Complicating matters, the town’s familiar intimacy forces Knock into unexpected emotional currents. A chance encounter with a charismatic resident awakens dormant feelings, while a sudden, enigmatic arrival from his former world threatens to unravel the careful façade he has built. These intersecting forces turn his meticulously plotted future into a delicate balancing act, where personal desire, professional ambition, and the pull of a hidden past converge, hinting at a story where the quiet charm of Saint‑Maurice may prove as unforgiving as any city’s shadows.
