Seven-year-old Wen and her parents, are vacationing at a remote cabin on a quiet New Hampshire lake, with their closest neighbours more than two miles in either direction. As Wen catches grasshoppers in the front yard, a stranger unexpectedly appears in the driveway. Leonard is the largest man Wen has ever seen but he is young and friendly. Leonard and Wen talk and play until Leonard abruptly apologises and tells Wen, "None of what's going to happen is your fault". Three more strangers arrive at the cabin carrying unidentifiable, menacing objects... Soon to be a major film, Knock At the Cabin.
