Like many a movie mystery, this one begins in the middle of the night when Toby, trying to deliver a package at Cary Grant's behest, finds himself with a corpse on his hands, a lump on his head, and an odd message from a dying man. In pursuit of a killer, Toby and Cary follow a trail of clues that leads them to a den of Nazi sympathizers and a nighttime confrontation on a mountain top.
