After winning a qualifying trial for a big speed-boat race in Santa Monica, California, Joe Dunn is offered a bribe, by gamblers, not to take part in the race and is so incensed that he starts a fight which lands him in jail. The girl he loves, Peggy McNeil, takes his place, but crashes into a buoy and is seriously injured---and Joe goes to desperate lengths to raise money for the services of a famous surgeon.
