Jo Van Fleet guest-stars as Amy Wilder, one of those peppery old eccentrics who loves animals but despises people. Coveting Amy's property, land developer Barton Roberts (John Crawford) hauls her into court to prove that she is mentally incompetent. Ben Cartwright invites Amy's long-estranged sister Margaret (Linda Watkins) to testify in the old woman's behalf-but Ben is for more than a few surprises. Written by Jack Miller and John Hawkins, "The Trouble with Amy" was originally telecast on January 25, 1970. ~ Hal Erickson, Rovi
