Pop Reeves, a competitor, finds that Turnberg had bribed his top man, Rogan, to lose, and fires him, and hires the Dawsons. His daughter Ann falls for Tim, yet it's Billy that wants her and proposes to her. She says no and declares herself to Tim. At the next big race, Rogan tries to cause Billy to smash, but he does instead, then accuses Tim of being responsible before dying. A police detective decides that Tim had done it so his brother could win, and leaves him one option, his brother must lose the upcoming Indy 500 or he'll know Tim's guilty.
