Margin of Error

A film crew is shooting an action movie on location - but more than one real killer is on the loose. A handsome film star walks into the newsroom - and Britt's life - to research his role as a government agent under deep cover as a reporter. But soon he needs Britt to run cover for him - as an obsessive stalker pursues the pair from the movie set to the city streets and to Los Angeles. But is the stalker the only one with murder on the mind? It's a story within a story, whose climax - deep within the bowels of the newspaper's vast press room - is deadly.
