More interested in partying and flirting with young musicians than work, veteran rock journalist Ellie Klug (Toni Collette) has one last chance to prove her value to her magazine's editor: a no-stone-unturned search to discover what really happened to long lost rock god Matthew Smith, who also happens to be her ex-boyfriend. Teaming up with an eccentric amateur documentary filmmaker (Thomas Haden Church in a delightful performance), Ellie hits the road in search of answers.
