Escape from San Quentin

Desmond plays convict Mike Gilbert, who goes on the lam with fellow prisoners Gruber and Graham when he finds out his wife is divorcing him and feels he has nothing to lose. Gruber intends to get his robbery loot, which his father, Curly, has successfully hidden from the law. After commandeering a plane, they double-cross Graham, who assembles his gang to get revenge – and Gruber’s loot. Meanwhile, Gilbert falls in love with Robbie, his ex-wife’s sister. Through Robbie’s influence, Gilbert decides to go straight, but his cohorts aren’t quite so willing to reform.
