The child of a mechanician is stricken with a malady which may require an operation at a moment's notice. He has to accompany his master, a racer, in a big auto race for a large prize, to run from their town to Los Angeles, fifty miles away. On the day of the race the child becomes worse. The parents know that an operation is necessary. The doctor cannot be reached. The mechanician takes the child, jumps into the car, and though he is the last to start in the race, he drives with such reckless speed that he comes in first and is awarded the prize. When he reaches Los Angeles, instead of stopping for congratulations from the crowd, he drives to the hospital. The child's life is saved.
