When someone frames me for rape and murder, I take it personal...

Mike Hammer steals a ride on a train upstate to Killington. But he arrives to a nasty surprise; he is accused by police of raping and murdering a young woman near the freight yards. Roughed up by the cops and facing a murder charge, Hammer's fate looks bleak until a beautiful blonde, Melba Charles--daughter of Senator Charles--gives him an unexpected alibi. But there is a price for clearing his name: he is to marry her.

Why would Melba jump in to save a man she has never met before? And, more to the point, where is the real murderer?
