On a cattle buying trip to Texas, Hoss and Little Joe are mistaken for a pair of hired killers recruited by a feuding family in their bid to wipe out a rival clan. Their efforts to convince the town otherwise are hindered by the fact that the Cartwrights are dead ringer for the gunfighters in question - Big Jack and Shorty Jim Slade. Written by David Bassler

The Cartwrights try to disprove the validity of a Spanish land grant to stop the De La Cuesta family from seizing part of the Ponderosa and all of the Carson Valley settlers' homestead lands.
