The Speed Limit

Tom Milburn, racing enthusiast experimenting with a new tire process, wants to marry Bess Stanton. However, her head is turned by a young man, Claude Roswell, driving a Rolls-Royce. The two men engage in a series of pranks culminating in Roswell's framing Tom for car theft. Tom's name is cleared, and so he is able to drive in the big race and test his experimental tires. The tires prove to be successful, and he wins the race, a manufacturer's royalty contract, and Bess.
