Secret agent Kelly Robinson is ordered to kill a double agent -- who turns out to be his old friend Russ Conley. When Kelly catches up with his target, Conley insists that he has been framed and begs Kelly to help prove his innocence. But does Conley mean what he says, or does he have a hidden agenda? David Friedkin, who co-wrote and co-produced this episode with Morton Fine, is cast as the enigmatic Conley. "A Cup of Kindness" originally aired on September 22, 1965. ~ Hal Erickson, Rovi
