The Big Caper.

Frank Harper talks his boss, Flood, into a more lucrative project to break into a San Felipe, California bank, which will be holding a million-dollar payroll for the Marine Base at Camp Pendleton. As a means to do this, Frank buys a local gas station and garage, and he and Kay pose as a married couple. Kay suggests buying a second gas station, and going straight and abandoning the criminal life. Frank eventually agrees to consider a romance with Kay, but only after the heist has been successful.
