When Buck Nation rides into Gunsight, he little knows what trouble awaits him. He has been left an abandoned ranch, but did its former owner really die in an accident? Questions mount and Nation is bushwhacked. Is Selby Rackham, the owner of the biggest spread around, the Grab All, somehow involved. Nation's quest to discover the truth takes him on a long ride from Wyoming, to Montana, with an old-timer, a woman, and a dog for company. On the way, it is not only Rackham's gun slicks they have to face, but the past with its buried secrets and hidden fears.
