The Cartwrights must carefully wend their way through Paiute territory, guarding two survivors of a recent massacre. One of the survivors, Josh Tanner (Steve Forrest), is an accused murderer. The other, Mary Burns (Tina Louise), knows that Josh is innocent, but can't-or won't-reveal this fact. This episode represented one of the first post-Gilligan's Island assignments for the toothsome Tina Louise. Originally shown on November 5, 1967, "Desperate Passage" was written by John Hawkins. ~ Hal Erickson, Rovi
