When a runaway asteroid threatens earth, retired astronaut Jack Rankin (Robert Horton) is ordered to take command of Space Station Gamma 3. At the expansive outpost, populated by a large contingent of soldiers and medical personnel, Rankin runs into old girlfriend Lisa (Luciana Paluzzi) and her fiance, Commander Vince Elliot (Richard Jaeckel), formerly Rankin's best friend. Rankin, Elliot and some men launch a rocketship toward the asteroid, laying charges there to blow it up before it reaches earth. The mission is a success, but a green, globby liquid is brought back to the station unnoticed, and, rising from the soapy green suds, little creatures grow and spread like a virus, creating hoards of clumsy but electrified and tentacled monsters!
