1950's America - Lanny Morris (Kevin Bacon) and Vince Collins (Colin Firth) are the country's most beloved entertainers. A classic double act at the top of their game when a scandalous murder mystery threatens their success and ends their partnership.

Fifteen years later, up and coming writer Karen O'Connor (Alison Lohman), decides to turn this cold case into a hot story. She wins a lucrative deal to write an expose about Morris and Collins and begins to ferret out the facts behind this fabled showbiz split. Her investigation leads to involvement, with both Lanny and Vince. But the more invested Karen becomes in the men and their story, the harder it is for her to accept disturbing truths about them and herself. What she finds is a serpentine, shocking tale of talent and treachery, love and lust, buried secrets and betrayed trust.
