: During a torrential rainstorm, two stranded young women, Genesis (Lorenza Izzo) and Bel (Ana de Armas), knock on his door asking to use his internet to find a taxi.

Knock Knock is not a masterpiece, but it is a . It works best as a dark comedy about male fragility and a satire of the "good husband" archetype. Love it or hate it, the film’s final image—Evan screaming "I didn’t do anything!" while tied to a chair—is an unforgettable snapshot of a man who never, ever learns his lesson.

The film plays with the dangerous trope of underage sexuality (even though the girls are revealed to be adults, they initially claim to be minors). This adds a layer of legal terror for Evan, threatening him with statutory rape charges, which creates a different kind of horror than physical violence.

On a dark and stormy night, he receives an unexpected knock on the door. Standing outside, drenched and seemingly lost, are two young women: Genesis (Lorenza Izzo) and Bel (Ana de Armas). They claim to be on their way to a party but have lost their way. After a moment of hesitation, Evan's good nature gets the better of him, and he invites them in to dry off and use his phone.

Eli Roth’s Knock Knock (2015) is a lean, modern riff on home-invasion horror that swaps supernatural scares for human malice — and asks whether a single night of temptation can upend a carefully ordered life. Starring Keanu Reeves as Evan, a devoted husband and father left alone during a storm, the film follows his decision to shelter two young women, Genesis (Lorenza Izzo) and Bel (Ana de Armas), which quickly devolves into psychological torment, blackmail and calculated cruelty. The result is a provocative, often uncomfortable portrait of moral collapse and the fragility of suburban complacency.

The film highlights how easily a comfortable, middle-class life can be dismantled. Evan’s smart home and artistic fortress provide no protection against human malice.
