It came from somewhere else (1988)

Howard Hassler's alien invasion film It Came From Somewhere Else concerns the effects of an alien invasion on the small Canadian border town of Grand Bosh. The befuddled sheriff is hardly able to function when confronted with citizens bursting into flame and body parts growing in farmers' fields. A group of high-school students believe they can save the town, but they can't even comprehend the force they are facing.
