The Cannes Film Festival! Most glamorous of all cinema occasions. In a luxury Riviera hotel the body of a beautiful film star lies prostrate. A hooded jewel thief breaks in and discovers her. A man bursts in and assumes the thief is the murderer. Another man enters and assumes another story. The film star wakes from her blackout and assumes a third story. The hotel manager arrives and attempts to make sense of all the stories.
A huge film premiere is looming, a diamond necklace has gone missing, scandalous affairs are about to hit the headlines, everyone appears to be trying to murder someone whilst blaming everyone else. Bodies and threats and alibis abound, and the plot thickens so fast it threatens to explode.
Never has the Riviera seen such a dastardly sequence of events! Never has Hollywood created such a catalogue of criminal conspiracies! Could real life ever be like this, or are show-biz temperaments simply running out of control? Bring down the curtain!
