A journalist who deals with the column "courier du cœur" has the absurd idea of launching an investigation into the death of a pianist whom he claims to have been murdered. To dazzle his wife, a reporter for the newspaper, he disguises the facts in such a way that the police suspect him, then declare him guilty. It takes a number of adventures to get him out of this mess and get him back into his section.
