Mayberry R.F.D. is an American television series produced as a spin-off and direct continuation of The Andy Griffith Show. When star Andy Griffith decided to leave his series, most of the supporting characters returned for the new program, which ran for three seasons on the CBS Television Network from 1968–1971. During the final season of The Andy Griffith Show, widower farmer Sam Jones and his young son Mike are introduced and gradually become the show's focus. Sheriff Andy Taylor takes a backseat in the storylines, establishing the sequel series. The show's first episode, "Andy and Helen's Wedding", had the highest ratings in recorded television history. Sheriff Taylor and newlywed wife Helen make guest appearances on RFD until late 1969, and then relocate with Opie. Mayberry R.F.D. was popular throughout its entire run, but was canceled after its third season in CBS's infamous "rural purge" of 1971. R.F.D. stands for "Rural Free Delivery", a quaint postal depiction of the rural Mayberry community.

Richard Kimble is falsely convicted of his wife's murder and given the death penalty. En route to death row, Kimble's train derails and crashes, allowing him to escape and begin a cross-country search for the real killer, a "one-armed man". At the same time, Dr. Kimble is hounded by the authorities, most notably dogged by Police Lieutenant Philip Gerard.

To scare the squatters from the cattle country he claims as his own, rancher Ed Sampson orders the Martin farm house burned. Galt Martin is killed, and his eldest son, Joe, is pistol-whipped. Timmy Martin sees the killer, Cass Becker and points him out when he and Joe are in Painted Flats. Cass forces Joe to put on a gun but Ned East, a retired gunfighter, saves the inexperienced Joe by forcing Cass to draw on him, and Ned is the winner.
