A band of evil creatures known as the "crites" bust out of a detention center on a distant asteroid and set a course for earth. Two bounty hunters with a reputation of causing trouble are immediately sent after them. When the "crites" arrive they immediately begin terrorizing the Browns, a happy-go-lucky rural family. The youngest of the family, Brad, sets out to find help, which he finds in the two bounty hunters who have caused a great deal of mayhem in the nearby community. Together they work to stop the "crites" and restore order.
