If Burt Gummer (Michael Gross) thought his graboid-battling days were behind him, he'd better think again. Grudgingly recruited to help the staff of a remote island research station that's under attack from the mammoth monsters, Gummer finds himself up against graboids that have been genetically modified by rich big game hunters looking for the perfect prey. Jon Heder, Jackie Cruz, Caroline Langrishe also star in the thrilling seventh chapter in the Tremors saga.
