When Francois, a journalist, tours a big store for an article, he is chosen by the son of the newspaper's owner, Rambal-Cochet, as his new toy. Needing money and unwilling to quit his job, Francois agrees to this ridiculous assignment. Gradually befriending the spoiled boy, he induces him to play at making a newspaper, unveiling publicly the tyrannical way of life of the father. The powerful emotional climax we experience with the child astonishes both men.

Unable to find her runaway son, a woman deceives two of her ex-lovers from her youth, a mild-mannered teacher and a tough journalist, that each is the real father in order to obtain their help.
