I Don't Know Much, But I'll Say Everything

I Don't Know Much, But I'll Say Everything (Je sais rien, mais je dirai tout) is a 1973 French comedy film directed by Pierre Richard.

Plot
Pierre Gastié-Leroy (Pierre Richard) is the son of a wealthy director of a factory of weapon manufacturing (Bernard Blier). Despite his parents, two generous uncles and a bishop godfather who try to inculcate in him the rigid values of his social level, Pierre is a dreamer, antimilitaristic, social educator who dreams of saving three thugs, his "little guys," at the limit of delinquency. After several resounding failures that sent him to prison, Pierre is ordered by his father to join his factory to direct the social service. Tired of the venality of his father and the foolishness of the "little guys", Pierre hires them at the factory. They will have fun making mischief and being overzealous to convince the supervisors on increasing the working rhythms, denouncing the trade union leaders, battling a strike and finally, stealing 500 tanks to sell them to the black market. A demonstration of new remote-controlled missiles attended by the Minister for Defence turns into a fiasco. Injured in his pride, the father Gastié-Leroy wants to show the reliability of his product by pointing the fire at his own factory.
