Jealousies and tensions in the AWB acting company explode when the body of one of their actors is found on the stage of the Bouwerie Lane Theatre, a sword from their current play, Hamlet, embedded in his chest. Mark Louis, an actor in the company, must use all of his investigative skills to exonerate Don Lovett, his best friend and fellow actor, who is accused of the murder. But where can he start? The body was found in the locked theatre and only four people have keys to the building, none of whom can possibly be a suspect. Little by little, Mark comes to what seems to be an impossible conclusion. With the help of New York City Detective Moriarty, the two men put on a little play of their own to unmask the murderer.
