Montmartre cabaret singer Vivien Romance is one of several people summoned by telephone to a mysterious rendezvous site by an unknown caller. Among Romance's fellow call-ees are antiques dealer Marcel Dalio, insurance agent Pierre Larquey, semi-retarded butcher boy Marcel Peres, and shady travelling salesman Georges Flamant. Each one arrives at the appointed place, assuming one of the others placed the call. Before long, the gathered strangers realize that a murder has been committed and that they're all prime suspects. Veteran movie-mystery fans will have no trouble figuring out the guilty party, but knowing who did it is not quite the same thing as knowing why. ~ Hal Erickson, Rovi
