Green Slime: The Premise
A large asteroid threatens collision with the Earth. Commander Jack Rankin is sent up from earth to an orbital platform to take command of a spacecraft and crew who will attempt to destroy the asteroid with nuclear charges. For some inexplicable reason, Rankin is also taking command of the orbital platform, currently under the command of Cmdr. Vince Elliot. Of course these men have a history. Part of that history is Dr. Liza Benson, who serves aboard the platform with Commander Elliot.
The ball of space rock threatening Earth is infested by globs of green goo that interfere with the mission by disabling equipment. The spaceship must attempt to outrun the nuclear blast by accelerating beyond its designed capacity. The mission to the asteroid is successful in blowing up the asteroid, the ship and crew survive, but a miniscule glob of the green goo hitches a ride along in a fold of a crew member’s space suit.
