Victor Martin (William Shatner) is a retired NASA test pilot often seen speeding around Palm Springs in his vintage Porsche convertible with his best friend Sal (Christopher Lloyd) in tow. His life changes when his license is revoked for drag racing and his car impounded. Forced to take public transportation for the first time, he meets his polar opposite Caroline (Jean Smart) and learns to navigate love and life again as he goes up against the state's new DA to get back his license and car.
