Eight college friends head to a "Haunted Rental" in a remote town for Halloween weekend, where they play Truth or Dare, the game rumored to have caused the deaths of seven teenagers decades earlier. What starts out as vodka-induced fun quickly turns serious when the dares become sickeningly dangerous and the truths threaten to tear the group apart. When players attempt to refuse the increasingly challenging tasks, they're met with deadly consequences that make clear: you must do the dare, or the dare does you. As the death toll mounts, the remaining players race against the clock to outrun, outsmart, and outlast the not-so-simple game of Truth or Dare.
