Gunsmoke: The Last Apache

After Marshal Matt Dillon (James Arness) receives a letter from an old acquaintance, a woman called "Mike" Yardner (Michael Learned), asking him to visit immediately, Dillon rides to the ranch. He finds it has been raided by Apaches, and Mike's daughter, Beth, has been kidnapped by a rogue Apache named Wolf. The bigger surprise for Dillon is learning that Beth is also his daughter, conceived while he had amnesia. Armed with the new knowledge of a daughter, Dillon sets out to rescue her.
