'Tis murder most foul when actor Franz Lachman (Jeff Morrow), starring in a stage production of Shakespeare's "Romeo and Juliet", is stabbed to death during Romeo's duel with Paris. There needs no ghost come from the grave to tell you that the police charge Steve Brock (Rex Reason), the actor playing Paris, with murder. In his efforts to save the star-cross'd Brock from the gas chamber, Perry Mason (Raymond Burr) concludes that "the play's the thing," wherein he'll catch the conscience of the real murderer. Thus, Perry moves the trial to the scene of the crime--then asks the "Romeo and Juliet" troupe to re-enact the events leading up to the moment that Lachman shuffled off his mortal coil.
