Knots Landing - Season 8 Episode 4 Past Tense

Flashback Scene: Mac tells Phil that the firm he is working for is involved with the mob, but Phil says he has a wife to support. Later Phil is indicted, and asks Mac to lie on the stand, but Mac says he can't. The polls begin to shift in Gary's favor. Peter decides to use married Gary's affair with Jill against him, although they've decided to hold off until after the election. Mac has a phony story released that they found the kidnapper's fingerprints and know who he is. This makes Phil very nervous, and Greg figures out that he is the kidnapper. Greg confronts him and gives him one day to undo the situation. Phil pours gasoline all over the house and lights a match. As the house starts to go up in flames, Karen discovers a trap door to the attic.
