Self-reliant 14-year-old Coley (Kevin Burchett) inherits a valuable gold mine from his otherwise luckless father. Having spent most of his life being rejected by the adult world, Coley suddenly finds himself in the middle of a custody tug-of-war between his long-estranged mother Margaret Claybourne (Patricia Smith) and his greedy uncle Caleb Melton (Dana Elcar). The Cartwrights' efforts to help the boy choose between his mother and uncle are stymied by the fact that Coley hates both potential guardians with equal fervor. Originally telecast on April 20, 1969, "Speak No Evil" was written by B.W. Sandefur and Norman Katkov.
