Murder Me Always

During an awful amateur performance of the play "Murder Me Always", an actual murder takes place off stage. The Director is shot. The "fake" murder mystery play comes to a screeching halt and a "real" murder mystery begins.

It seems that the "Murder Mystery Murderer" is on the loose and has struck again. Fortunately, Detective Joe Mamet, a Raymond Chandler Pulp type gumshoe had the production on a stakeout and he rises to the occasion to begin an investigation into this real mystery.  Could it be that one of these very bad actors is really a very bad person?

Will this "real" murder mystery be any better than the fake one? Is art imitating life? Is the play really the thing? Is this the original play that went wrong?
