A young woman with a long rap sheet who steals cars for a living is befriended by a public defender who tries to steer her straight. But her goal is to steal and subsequently sell enough cars (sometimes the same car more than once) to buy a new Ferrari.
Just like everyone else, I had never heard of this film until it was shown on Turner Classic Movies. And I can understand why it faded away. There is little that stands out about it, and the two stars are not anywhere near A-list (with all due respect). So it makes sense that this would be buried.
But it is not a bad movie by any means, and a fun film. Since it was apparently made by MGM, I would suspect the rights to distribute it are fairly cheap right now (2017) and it might be the kind of title that a specialty Blu-ray label would pick up.
