Samantha helps a little boy named Johnny Mills practice for a Soap Box Derby. After Gladys brags about how her nephew will do better than anyone there, Samantha helps Johnny out, repairing a wobbly wheel with a twitch. Samantha tries to get Johnny's father involved, but he wants Johnny to attend college and become a doctor, not a race car driver or mechanic. At the Derby, Gladys and Darrin keep a sharp eye on Samantha so that she doesn't help Johnny, but magic is unnecessary when Johnny wins on his own merit. The announcer wants to congratulate Johnny's father, who isn't there to see his son triumph. Samantha pop's back to Johnny's father's garage, who is too busy to break free. Samantha repairs a carburator and 3 tires, encouraging Mr. Mills to rush to the Derby for his son.
