The story begins with a meteorite entering Earth's orbit in the Arizona desert, near where Steve, a wannabe firefighter, lives. A group of professors, including Professor Kane and Professor Harry, discover that the meteorite contains an alien rock that can bleed and is home to single-celled organisms that can evolve rapidly. These organisms quickly adapt to Earth's environment, evolving into more complex life forms, including insects, worms, and even a dragon-like creature.
As the creatures begin to wreak havoc on the city, the professors, along with Dr. Alison and Steve, team up to stop them. They discover that the aliens are vulnerable to selenium, which is found in anti-dandruff shampoo. The group decides to use the shampoo to defeat the creatures, and in a bizarre and humorous climax, they successfully kill the alien dragon by giving it an enema with the shampoo.
In the end, the heroes are celebrated, and Steve's dream of becoming a firefighter comes true. The movie ends with a comedic twist, as the actors promote Head & Shoulders anti-dandruff shampoo.
