Helen grabs her bags and heads for the train and coincidentally Sam does too pushed by his close friend Marty Waterman (Elisha Cook, Jr.) who stays in Reno to get details on the murder and agrees to meet Sam later. Coincidentally Sam and Helen meet on the train and are attracted to each other in part because in a casino earlier they had flirted across the Craps table.

Sam sees a good thing in Grace and successfully seduces her into marrying him partly for the power her money can bring him but also to sustain the attraction he has for Helen.

Sam reacts in a jealous pique and Helen realizes that he must be stopped and calls Arnett to bring the police with the information he has gathered from his investigation. Sam discovers Helen's communication with Arnett and pulls his gun just as the police arrive resulting in a climactic shootout.
