A high profile trial is taking place in San Francisco but the testimony of Helen (Mary Beth Hughes) can put the rich defendant away. Shayne is tasked to bring Helen back from Denver, but the defendant has hired various men to try and stop them.
Helen meanwhile is tiring of her role in the spotlight and falls in love with Everett (Louis Jean Heydt) who is having a mid-life crisis. Shayne also has to handle his journalist old flame Kay (Lynn Bari) meddling in his affairs...
A great crime B-movie that takes place mostly in the claustrophobic confines of a railway train. A lot of story is packed into these railway cars too. The story moves as fast as the train does.
