When a wealthy trophy hunter genetically modifies Graboid eggs to create the ultimate hunting experience, it isn’t long before his prey escapes the confines of his small island and terrorizes the inhabitants of a nearby island research facility. The head of the research facility and her second-in-command locate the one man who is an expert in killing Graboids: Burt Gummer (Michael Gross). Once on board, Burt leads the group in an all-out war against the larger, faster, and terrifyingly intelligent Graboids and the swiftly multiplying Shriekers.
