Adolescent French suburban lower-middle-class nerd Marc Morel was happy being the teacher’s pet and school representative in a Latin competition. Until he meets and instantly falls in love with fatherless semi-illiterate shop clerk and ditto-daughter Martine Pérez.

Cool big brother Christian, a photographer, tries a more understanding approach, but even that runs into trouble.
