Off the Washington coast, on a secluded island cabin, Brie, her boyfriend Steve and four other old school friends assemble for an unforgettable Fourth of July celebration. Obviously, the gang intends to party hard, unfortunately though, they will fall victim to the sinister plans of a fanatical terrorist organisation, when the friends without knowing it, they will share a batch of genetically modified cocaine that transforms one into a ravenous, bloodthirsty cannibal. Eventually, as Brie still remains unaffected, she must gather up all her remaining courage and fight to survive this madness.
