Donkey Punch

A luxurious yacht becomes a deadly playground for a group of English teenagers on holiday in Spain, where a night of partying and debauchery quickly turns into a weekend of bloodlust and terror. Three hot girls and four young men invite each other to their private revelry, but one act of deviancy will prove too far, unleashing a bloody bedlam that will leave only one survivor. As the group's darkness descends into chaos, the lines between friend and foe blur, and the survivors are forced to fight for their lives against the men who once welcomed them aboard with open arms.
