Wonderland (2003/ Blu-ray)

On the afternoon of July 1, 1981, Los Angeles police responded to a distress call at 8763 Wonderland Avenue in Laurel Canyon and discovered a grisly quadruple homicide. Drug dealers Ron Launius, Billy Deverell, Barbara Richardson and the homeowner Joy Miller were found brutally murdered, bludgeoned to death with lead or steel pipes, and Launius's wife, Susan, was left in critical condition. The police investigation that followed -- led by detectives Sam Nico, Louis Cruz and Mike Peters -- would unearth a seedy world of drugs and violence, ultimately revealing a motley crew from L. A.'s underbelly including ex-con David Lind, nightclub impresario Eddie Nash, and porn legend John Holmes as well as Holmes's estranged wife Sharon and his teenage lover Dawn Schiller.
