What begins as a seemingly innocent invitation to dinner from a relative stranger turns into something more sinister. Persuaded to stay for three days in the stranger’s isolated house, the guest hears six bizarre stories of people known to the host. The last of these chilling tales concerns the host himself and has an alarming ending. When the guest returns to his own home, the tales he’s heard continue to haunt him and where they lead makes his own story the strangest of all.
