Plot Synopsis

With the help of best-selling crime novelist Michael Connelly, this four-part documentary explores the twisted story of the massacre at Wonderland Avenue on July 1, 1981 -- one of Hollywood's most famous murder cases that inspired the movie BOOGIE NIGHTS. This case symbolized an era in Los Angeles -- involving sex, drugs, rock n' roll... and murder. In noir-style, verite interviews, Connelly seeks key details about this gruesome quadruple murder with the original detectives, prosecutors, and undercover cops he'd come to know as a young crime beat reporter for "The Los Angeles Times." As the investigation unfolds, weaving in rare archival footage and photos, a colorful cast of characters emerges -- famous porn star John Holmes, drug dealers and kingpins, mafiosos, televangelists and multiple celebrities, including Liberace and his boy toy, enigma Scott Thorson. In a game of cat-and-mouse, Connelly tries to pin down the facts of Thorson's many larger-than-life and stranger-than-fiction stories. After four decades, Thorson may be the last man standing between the crime and the truth. But should anybody believe him?
