As a wagon train beds down for the night, the travelers gather round the campfire to listen to legendary frontiersman Jim Bridger spin his usual yarns and tall tales. But this night, prompted by the appearance of a striking redhaired woman, Bridger tells his most implausible story of all. To the disbelief of his listeners, Bridger claims that he was once killed by a party of Blackfeet warriors yet lived to tell the tale. His story takes place 20 years earlier at the legendary fort Bridger, which he built at the edge of the wild frontier. When a party of trappers goes missing, Bridger sets off from the Fort to find them, but he ends up being hunted by a party of Blackfeet warriors in a deadly game of cat-and-mouse. After hours on the run, he is surrounded by the advancing war party, with no way of escape. With the help of the mysterious redhead, Bridger soon proves that he really did come back from the dead.
