Bonanza star Michael Landon both wrote and directed the poignant episode "Don't Cry, My Son." After the death of her baby, Ruth (Diana Shalet), the distraught wife of an overworked doctor (Richard Mulligan), walks out on her husband. Unhinged by this, the doctor kidnaps the newborn child of the woman he is presently caring for, imagining that the infant is his own child. "Don't Cry, My Son" was first broadcast on October 31, 1971. ~ Hal Erickson, Rovi
