The Deputy - "Mother and Son" (1960)

In this episode of the Western drama, The Deputy, Marshal Simon Fry (Henry Fonda) paroles the brains behind an outlaw gang so that the young man can visit with his mother, who is unaware of the man's criminal activities. Franciscus plays the son (and gang leader) of the episode's title, William Stanhope. Interestingly, this is one of the episodes of this series in which Fonda played a substantial role (in most of the show's episodes, Fonda only appeared briefly in the start and end, although he narrated all of them), convincing Stanhope to turn on his own gang.

Also of note is Fonda's relationship with Franciscus - who might well have been Fonda's own "son" (-in-law) had Jane Fonda agreed to marry Franciscus when he proposed to her (as told in "James and Jane", March, 2011).
