"In Hollywood, secrets can wield tremendous power. Some would kill to keep their secrets. Others would kill to learn them." June, 1938. Hollywood, California. Clayton Mosby is waiting on the corner of Sunset Boulevard and Gower Street, an area known within the motion picture industry as "Gower Gulch." Soon a truck from Republic Pictures will arrive to round up extras for one of their low-budget westerns. Clay, a down-on-his-luck former Texas Ranger, is just hoping for a few days of work as a movie cowboy. He could sure use the money. Money is no problem for Irene Durand, the beautiful actress who is Monarch Pictures' biggest star. Her problem is blackmail, and she's willing to pay handsomely to make it go away...quietly. Around Hollywood Clay has become known as "The Gunslinger." It's a reputation he despises. But "The Gunslinger" is exactly who Irene is looking for. And the money is certainly tempting. Almost as tempting as Irene herself. But Clay soon discovers he's drawn the attention of Eddie Kessler, Monarch Pictures' notorious "fixer," who has designs on the beautiful actress. Kessler is accustomed to getting what he wants, and he wants Irene Durand. Blackmail suddenly turns to murder as Clay finds himself entangled in a deadly Hollywood plot of secrets and lies...a plot in which "The Gunslinger" has become both the hunter and the hunted.
