Will Keen lives in two different worlds - one white, one Paiute Indian. He guides wagon trains into Oregon Territory, braving savage lands and equally savage men - of all races - who prey on innocent wagon families. After a decade in the job, Will has no idea that his future will take a different turn with his current assignment. Badly injured after fending off an attempted robbery, he must teach a young woman, Sarah, how to guide the train. Love blossoms between them - but an outlaw is hell-bent on revenge...
