Bonanza - Silent Thunder ( Dec. 10, 1960)

⁣
Stella Stevens guest-stars as Ann Croft, a sheltered deaf-mute girl. Joe Cartwright tries to teach Ann sign language, only to be thwarted by the girl's fiercely overprotective father Albie (Albert Salmi). In the course of John Furia Jr.'s teleplay, Ann ends up saving her father's life, and also falls in love with Joe (the kiss of death for any Bonanza leading lady!) Also appearing are Kenneth McKenna as Sam, James Griffith as the Preacher, Sherwood Price as Eb and Harry Swoger as Tom.
