A Chicago gang led by Slade carries out an audacious brokerage robbery. Lieutenant Bill Mason takes the case, continuing his friendly-enemy relationship with crime reporter Ann Rogers. One gang member is caught; eventually, others follow. But Mason hasn't a clue to Slade, principally because he's unaware she's a woman.
