Perry Mason: The Case of the Defiant Daughter synopsis
Richard Stuart (Robert Culp) blackmails many of his patrons for money, including the brother of David Benson. After his brother commits suicide, David arrives at Stuart's Las Vegas gambling party, threatens him with a gun but ultimately cannot kill him.
