Based on Nikki Sixx's drug-soaked New York Times best-selling memoir, The Heroin Diaries, chronicles the year of decadence and depravity that almost cost Sixx his life during the recording and tour for Mötley Crüe's seminal 1987 album, Girls Girls Girls, the book not only became a worldwide best-seller, but also spawned the band Sixx A.M.
