Fly, Baby, Fly - S1.E9

Johnny is hired by tough-guy millionaire Guy Fletcher to transport a locked valise containing valuable gems to Arizona. Once aboard the plane Johnny meets Nina, who turns out to be Fletcher's beautiful wife. This is no coincidence, however, as Johnny learns he isn't carrying jewels after all. Fletcher has provided him with a bomb set to explode during the flight, in an insidious plot to murder her.
