Night of the Creeps | 1986
In 1959, an alien craft crashes to Earth. The ship contains sluglike parasites that take over their hosts, turning them into murdering zombies, and one of these kills a young person on lover's lane. Then in 1986, a couple of nerdy college boys come across that body, which has been cryogenically frozen in their science lab, and steal it for a prank. When the parasite from outer space breaks free of hit host, it quickly begins infecting the student body.
