影片故事从两群人讲起，一是一群学生，另外一群人则是一伙犯罪集团，他们被一只史前巨鲨围困在了一座小岛上。岛上曾一度被用于非法钻井，油井在不经意间惊醒了这头沉睡在海底的史前鲨鱼。When an oil company unwittingly unleashes a prehistoric shark from its icy prison, the Jurassic killer maroons a group of thieves and beautiful young female college students on an abandoned piece of land. Unable to escape the fearsome beast, the two groups of strangers must put aside their differences and come together to fight off the extinct, ferocious monster whilst battling for their lives. What started out as some fun in the sun, ends up as a survival of the fittest as nature's cruelest creation has come back from extinction and he wants revenge!
