In a first-time production by television comedians and café-theater actors, this is a slightly shallow comedy about a novice private detective and his cohorts, out to capture a feared "telephone killer" who strangles his victims (all female) with a phone cord. "The Commissioner" (Jean-Claude Brialy) runs the police investigation -- a kind of investigative competition with the amateur sleuths. A series of episodic sequences, comedic situations, and gags carry the action through to the final roll of credits, helped only a little by cameos from Michel Galabru, Jean Yanne, and others.
