Eric and Andrew, with seven-year-old Wen, are vacationing at a remote cabin on a quiet New Hampshire lake. When Leonard appears in the driveway, he is the largest man Wen has ever seen, but he is young, friendly, and he wins her over. Leonard abruptly apologizes and tells Wen, "None of what's going to happen is your fault". Three more strangers then arrive at the cabin carrying unidentifiable, menacing objects.
