In Spite of Danger

Bill Crane, a skilled race-car driver, suffers an accident on the track that ends his days on the fast-paced circuit and leaves him unable to return. In search of a new vocation, he meets Sally Sullivan, who runs a roadside lunch wagon, and she helps him land a job as a truck driver. They fall in love and marry. He receives a contract to haul a load of dynamite, and during a perilous descent down a mountain, the brakes on his truck are sabotaged—just as the brakes on his race car were sabotaged.
