Roth also co-wrote the script with Guillermo Amoedo and Nicolás López. Inspired by Peter Traynor's 1977 film "Death Game," "Knock Knock" casts Reeves as Evan Webber, an ostensibly generous architect whose family is away for the weekend.

His wife Karen (Allamand), a thriving artist, leaves their assistant Louis (Burns) in charge of her sculpture that needs to be transported to an art gallery. Alone in his exquisite and expensive home, Evan works on the details of an ongoing house project.

When Webber hears a knock at the door, he discovers the young and beautiful Genesis (Izzo, Roth's wife) and Bel (Armas) standing in the torrential rain.

Genesis and Bel say they are trying to get to a party close by, and Webber, in due course lets them in so that they can sort out where they need to go. When the girls try to seduce him, Webber initially repulses their sexual advances. But he eventually agrees to a threesome in the shower.  

Genesis and Bel chase him with a gun. They tie him up with a hose and torture him in all possible ways.

Genesis shows Evan the explicit video she recorded earlier with his phone of him and Bel. As an appalled Evan watches on, she uploads it to his Facebook page. In the end, they spare Evan's life, revealing that they were playing a perilous seduction game and that they are used to trick fathers.

Karen soon arrives to find out her sculptor, home, husband, and life completely ruined. The movie portrays the disadvantages of social media in the contemporary world.

"Knock Knock" has received mixed reviews from critics. Review aggregator website Rotten Tomatoes reports a 37% rating based on 27 reviews, with an average rating of 5/10. On Metacritic, the film has a score of 60 out of 100 based on 9 critics, indicating "mixed or average reviews".
