When five American students arrive in Ireland to go on a camping trip with their old buddy Jake, they are in high spirits. Jake has promised them the 'trip of a lifetime' because he claims Ireland has the best magic mushrooms in the world with the highest potency!

Now they are tripping things don't seem so funny. Bluto, one of the gang is missing. Tara thinks he's dead because she feels she has seen his death before but nobody believes her, they think she is just wasted. As their paranoi grows so does the fear of something watching them. something that is after their blood and won't stop till they all get wasted.
