La Scarlatine (1983)

In a building on the Boulevard Haussmann in Paris lives ten-year-old Roger, who is surrounded by women - his great-grandmother, his grandmother, and his mother Nicole. Living in an exclusively feminine environment, the boy wishes more than anything else to have a masculine presence around. His dream comes true when he meets Jacques, who's madly in love with Nicole and who is about to completely turn the boy's life upside down.
