A mentally-unstable man finds his slow side into insanity hastened when he walks in on his wife and his best friend having sex, and embarks on a vicious killing spree that culminates in a shocking act of brutality. Mike Strauber was never a picture of mental health to begin with, but after becoming the victim of the ultimate betrayal, his odd fixation with the game "Truth or Dare?" becomes an outright obsession. Now, anyone unfortunate enough to cross his path will be forced to play, and odds are it'll be the last thing they ever do.
