Dr. Samantha Goodman, an attractive psychiatrist in her thirties, joins her husband and sister for a weekend at a winter cottage when an unexpected guest arrives. Harlan Pyne, a violent sexual offender, is convinced that Samantha conducted unethical experiments on him while she was his doctor. With the assistance of his troubled yet eager protege, Harlan forces Samantha and her family to participate in a series of nightmarish games. On this night of terror, escape is not an option, truth guarantees nothing, and revenge will not necessarily be sweet.
