Knock Knock. Evan (Reeves) seems like the perfect guy. He’s an architect, lives in a beautiful California home, has two kids and a lovely talented wife. One afternoon, the wife and kids go to the beach but Evan has to stay home and work. It’s raining, he’s alone, listening to music, and there’s a knock at the door. Two beautiful young girls, played by Ana De Armas and Lorenza Izzo, are standing in the cold. They’re drenched, lost and just want to come in to dry off and use the phone.
