Grant Diamond is a professional gambler on the run from his past. When he comes across a wagon wreck, the chance to escape his pursuers is too good a gamble to pass up, and he assumes the identity of the dead wagon driver. His plan takes an unexpected turn when local heiress Lily Rose mistakes him for the missionary she had asked to come work with the Wiyot Indians. Seeing Eureka as a promising place to lay low, Grant plays along. Before he knows it, he's bluffing his way through sermons and building an Indian school. But with a Pinkerton on his trail and a rancher rousing fresh hatred against the Indians, Grant fears the new life he's built may soon crumple like a house of cards.
