Joan Ross has been haunted by the assassination of JFK since childhood. Now an acclaimed reporter and seasoned researcher, she has been re-reading the Warren Commission report, reviewing old television footage and generally immersing herself in the 'facts' from that period. Most of it, she finds, is pure bunk.
Ira Basil is a well-regarded Hollywood screenwriter known mainly for light comedies - his first foray into drama went so poorly he's afraid to pick up a pen. So when Joan enters his life to help him with his next project, he just knows his career will get back on track.
Together they begin to work on a script that's loosely based on a 'true life' mystery: Jack Ruby as a mafia wanna-be conned into doing a big job for the mob. But when art begins to resemble life, bad things begin to happen to Joan.
