A two-fisted and taciturn Texas sheriff, Burt Sullivan, is a man committed to duty and justice but possessed by a desire for revenge.

Sullivan, along with his younger brother, crosses the border to bring wealthy and sadistic Mexican crime boss Cisco Delgado (José Suárez) to justice for the murder of their father.

Eventually joining forces with a group of Mexican revolutionaries, Sullivan and his brother soon find themselves at the center of a bloodbath.

Texas, Adios, like many Spaghetti Westerns, was shot in the Spanish province Almería.

Franco Nero, in his comments on the Anchor Bay DVD, mentions that the Texas, Adios shoot took place not far from where Sergio Leone was filming The Good, The Bad, and the Ugly at the same time.
