A hired gun became caretaker for his dying sister's four young children in the 1890s mining town of Paradise. As the show began its third and final season, the title was changed to `Guns of Paradise' and the reformed gunslinger became the new marshal. In a salute to 1950s TV Westerns, Hugh O'Brian and Gene Barry, the stars of `Wyatt Earp' and `Bat Masterson,' reprised their roles for a two-part episode.
