Just after a jury finds Ann Grey guilty of murder, the car carrying her to prison crashes into another car. Ann escapes and ends up in lawyer Tony Baxter's car. Tony realizes Ann is innocent, so he vows to help her prove it, risking his neck in the process. Tony and Ann are pursued by the police and by Smiley Gordon, a mob boss who engineered Ann's escape thinking that she can lead him to a $250,000 stash.
