The last known surviving witness in the case, Scott Thorson, shares what he overheard the night of the murders, as well as the details of his extraordinary life with Liberace, Hollywood elite and the drug underworld of 1980s Los Angeles.

Scott Thorson tells of building a drug empire in Hollywood in the 1980s while the crack epidemic in Los Angeles explodes, all before being discovered as the missing puzzle piece to the Wonderland case almost a decade after the murders.

In 1990, Scott Thorson testifies against the alleged mastermind behind the massacre at Wonderland. The trial doesn't go as planned, and Thorson enters witness protection. What ensues is a stranger-than-fiction series of events… if we believe him.
