A group of strangers, ten in all, are invited by a Mr. Owens to spend a weekend at his remote mountaintop home. After dinner, they learn via a tape recording that they've been invited to the house to pay for their crimes. The accusations are well-founded, and unable to leave the house, the guests are being killed off one by one. The private detective in the group thinks that their host is likely hiding in the house somewhere. Judge Arthur Cannon thinks the killer is a member of the group and he proves to be correct.
