Automotive test driver Terry Martin (James Stewart) couldn't get the powers that be at his Detroit plant to buy into his theories for a more efficient carburetor. Managing to make an ally─and maybe more─out of the boss's daughter (Wendy Barrie), he might get the chance to prove himself to the world on no less a stage than the Indy 500. M-G-M "B" that gave Stewart his first lead opportunity co-stars Una Merkel, Ted Healy, Ralph Morgan. 70 min. Standard; Soundtrack: English Dolby Digital mono.
