"A Season In Purgatory" is a movie inspired by the true story of Martha Moxley. The movie debuted as a CBS mini-series in 1996 starring Patrick Dempsey, Brian Dennehy, Sherilyn Fenn and Craig Sheffer. The film is based on the novel by Dominick Dunne by the same title.
Directed by David Greene, " A Season In Purgatory" is a sensational movie that follows the case of the handsome Harrison Burns, a man who knows a terrible secret: A young girl was murdered one night many years ago, and the person responsible is a friend from a prominent, political family. The movie weaves through a complex cover-up that deeply disturbs Harrison Burns. Can he keep the family secret or will he break?
The true story that inspired the book and the movie is that of Martha Moxley, a beautiful, blond teen who disappeared from her home after spending time with some neighborhood friends in 1975. Moxley's dead body was found only yards from her Greenwich home. An autopsy examination concluded that the girl had been badly beaten with a golf club.
The murder went unsolved for decades. Though some speculated that a neighborhood boy, Michael Skakel, had committed the crime. Skakel was eventually arrested and convicted of the murder decades later but that conviction has since been overturned, according to CBS News.
There is another movie based on this same case entitled "Murder In Greenwich."
