250 million years ago, a carnivorous species 'planted' a crop of humans on an uninhabited planet known as Earth. Now, the alien life form has returned to harvest its yield. With total destruction looming just moments away, a futuristic warrior and a prophetic mental patient join forces against the creatures, but with mortal weapons no match for the superior alien technology, the duo's only hope for victory lies in finding a 250 million year-old spaceship known as Laserhawk. The future of the world depends on it.

When the police discover that a mob hitman has moved in next door to the Robbersons, they set up a stakeout in the Robbersons' home. Hard-nosed, tough-as-nails Jake Stone and his young partner Tony Moore are assigned to the stakeout, but now it is a question of whether Jake can last long enough to capture the bad guys. The Robbersons want to help, and by doing so, drive Jake crazy.
