When a devoted husband and father is left home alone for the weekend, two stranded young women unexpectedly knock on his door for help. What starts out as a kind gesture results in a dangerous seduction and a deadly game of cat and mouse.
As a piece of social satire, "Knock Knock" winds up being not just toothless but anticlimactic.

The characters are driven by convenience, not behavior, and their actions seem like they've been manhandled into place to make the plot work.
