Livia Saint is a primary villain in the 2004 film The Punisher. She is the wife of Howard Saint, the film's main antagonist. She ordered the entire family of Frank Castle to be murdered when her son was killed during one of Castle's undercover operations. Castle, however, emerged the lone survivor of his family's massacre five months later.
Frank tricked Howard into believing that Livia was having an affair with his best friend, Quentin Glass, who unbeknownst to Howard was a closeted homosexual. After murdering Quentin in a jealous rage, Howard confronted Livia about the "affair" and showed her Quentin's body wrapped in a carpet. Horrified, she revealed to Howard that Quentin was gay but he believed that she was lying. Howard threw Livia over a bridge. Landing on a train track, she had no hope of escape and was subsequently killed by an oncoming train.
Livia did not know that she was being set up by Frank Castle as part of his mission of revenge and punishment.
