 Danny Mitchell (Ted Donaldson), feeling that he has been misunderstood (nothing new for this kid in this series) by his parents, (Tom Powers and Ann Doran), takes his dog, Rusty (Flame the Wonder Dog), and leaves home, camping out near the trailer of veterinary Dr. Francis Xavier Ray (Aubrey Mather). Gas escapes in the trailer during the night, and Rusty rescues the vet before he is overcome.
