Tom Guthrie's plan to hide his wounded friend, Billy the Kid, from a vengeful U.S. Marshal at Bret's ranch threaten to spoil the ex-gambler's barn-raising.

Bret wins a stolen horse in a poker game that Teddy Roosevelt was supposed to give as a gift to Geronimo to seal a new treaty and the young Congressman is desperate to recover the animal in time. Meanwhile, Tom tries to swing a business deal with several shady operators to build a new ice house using the Red Ox saloon and Maverick's ranch as collateral.
