Whilst taking part in the Tour De France, Champion is kidnaped by the mafia. His loving grandma who has raised him since his parents died, Madame Souza, and her overweight dog, Bruno, embark on a journey to track him down. They get as far as the town of Belleville, but the trail goes cold. Then they meet the Triplets - three elderly sisters who have retired from the vaudeville scene - and together they begin their hunt afresh. Eventually they manage to discover where Champion is being held and attempt their daring rescue. As well as being one for older children and adults alike, this charming and delightful film is also an homage to the history of cinema and will keep the most hardened film buff entertained.
