Falcon Crest (1981) : 9x19

Richard knows that Sharpe was behind the sabotage that almost killed his son, Danny, and he has Johnny Sacco, the mechanic paid to tamper with Sydney's car, to prove it. In order to keep Danny and his estranged wife Anne from knowing his involvement in the accident, Sharpe transfers ownership of Falcon Crest to Richard. After Anne agrees to give her marriage with Sharpe a second chance, she changes her mind when Johnny Sacco arrives intoxicated at the Sharpe residence and tells Anne everything. Anne lets Sharpe in on a secret she's kept for 21 years: Richard is Danny's real father. After several months in a coma, Angela revives.
