A group of curious American teenagers is promised the 'trip' of a lifetime by their Irish friend and mushroom expert Jake. Once in Ireland, they ignore Jake's warnings about the 'shrooms they shouldn't eat' and things start to go wrong. Afflicted by horrific visions, they can no longer distinguish gruesome apparition from shocking reality and the group is bloodily whittled down to one. Real or not, these visions leave behind a real enough trail of blood.
Release Date: Nov.23, 2007 at all UK cinema.
