Drew Barrymore, Alyssa Milano and Noëlle Parker all took stabs at portraying the disturbed young lady, yet a true on-screen depiction of Amy Fisher has never emerged - until now. In this Rashomon of found footage film, director Dan Kapelovitz mind-melds the multiple melodramas into one ultimate metadrama mashup.
