Missing for two years and presumed dead, hard-hearted businessman Hartley Bassett (Thomas B. Henry) suddenly returns and begins make everyone's life miserable all over again, especially his wife Sybil (Peggy Converse). After he fires his heir apparent Peter Dawson (Philip Ober), Bassett is murdered and Dawson is accused. Perry Mason (Raymond Burr) is approached by two eyewitnesses, Richard Hart (a young Robert Redford) and his wife Teddi (Cindy Robbins), who can prove that Bassett is innocent. There are only two problems: each witness claims that a different person is the guilty party--and both witnesses abuptly vanish just before the trial! This is the first episode of Perry Mason's fourth season.
