"The town of Hackamore, Arizona, needed someone who could stop the G Bar outfit from terrorizing the town. After much debate, they settled on Lum Martin, express messenger, border deputy, and gunfighter. He agreed to take the job if they would let him hire Syc Brown as his deputy. The wires summoned Sycamore Brown from his peaceful Papaguería home and he came to be the outfightingest fool in Arizona. Lum and Syc, along with another deputy, Jack Haines, soon brought peace to the town. Fearing trouble would erupt as soon as the three men left, the town decided to retain all three peace officers. But a peaceful town can become boring and Lum and Jack started to joke that they could rob the express shipment, lead a posse in an unsuccessful attempt to catch the robbers, and after things quieted down leave town as very rich men. They brought Syc in and gradually it turned from a joke to a plan. When the time came, everything went according to plan. Now it was just a matter of waiting until the robbery was old news and they assumed the robbers were long gone. But railroad detective Sam Slocum wouldn't give up and greed and impatience soon pointed toward the guilty men. Now it was each man for himself and Syc was fighting for his life."--
