Lucky and Jolly Jumper were looking forward to some rest in Texas, but are approached by Mexican Sanchez to save from lynching by ruffians his crazy friend, who believes to be Don Quichote since he fell on his head. They have no luck finding Cervantes's book to prove that's a fictitious character, and the knight looses his chivalrous heart to a bar girl he takes for his Dulcinea. When she tells him her farm was stolen, the don rides off against the 'black knight', but in the wrong direction, to an Indian tribe which believes madness comes for the Great Manitou.
