Dr. Samantha Goodman (Kate Greenhouse
), an attractive psychiatrist in her 30s, joins her husband and sister for a weekend at a winter cottage when an unexpected guest arrives. Harlan Pyne (Aidan Devine
), 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 protégé, Harlan forces Samantha and her family to participate in a series of nightmarish games--games tinged with psychological and physical torture that are designed to both deliver the truth and reap vengeance. On this night of terror, escape is not an option, truth guarantees nothing, and revenge will not--necessarily--be sweet.
