Tremors

Shriekers are spotted in Juniper, Arizona and Twitchell sends Burt and Tyler to handle the situation. However, the Fish and Wildlife Service are also in town and manage to kill five Shriekers. They also take one alive for study and when it gets a hold of some food, the Shriekers start to multiply again. Now Burt and Tyler have to stop them from massacring the entire town.

Burt finds and kills a Shrieker in the valley, only to learn it was a part of a government funded project to train Shriekers for rescue missions. But when a storm knocks out the equipment controlling them, the remaining Shriekers escape and multiply. Now to survive, the Perfection residents must make a stand at Burt's place.
