The Johnsons are a family of animal trainers who specialize in preparing animals to do film work from their California ranch. But when a mountain lion escapes from a movie set, the people living there are frightened for their safety and demand that the animal be killed. What they don't know is that it's a wild lion that's causing trouble, not the Johnsons' protégé. Co-stars John Savage, David Leisure and Debby Boone.
