With his wife and two children away for the weekend on Father's Day, happily married suburban dad and successful architect Evan Webber hears a knock at the door in the dead of night during a violent storm. Before him, two stranded and soaking-wet friends, Genesis and Bel, ask for help and a place to stay while waiting for a taxi; however, pretty soon, things will take a dark turn for the unexpected when the pair of tempting femme fatales seduce Evan into bed with them. Now the stage seems to be set for a dangerous game of cat and mouse as the girls have their way with the unwitting Good Samaritan. Can Evan save his marriage and, above all, his life?
