Two American college buddies Paxton and Josh backpack through Europe and along the way pick up a new friend named Oli, an Icelander who is also travelling. During their search for narcotics and women Paxton and Josh are eventually lured by a fellow traveler to what's described as a nirvana for American backpackers –a particular hostel in an out-of-the-way Slovakian town stocked with Eastern European women as desperate as they are gorgeous. On the train they meet an odd surgeon who takes a liking to Josh. Soon the three friends arrive and easily pair off with exotic beauties Natalya and Svetlana. In fact, too easily... Initially distracted by the good time they're having, the two Americans quickly find themselves trapped in an increasingly sinister situation when their friend Oli mysteriously disappears and soon what they will discover is the darkest, sickest recess of human nature – if they survive.
