The Belle and Sebastian franchise refers to the popular series of stories about a boy named Sébastien and his large, intelligent dog, Belle, which originated as a French television series in 1965 and has since expanded into novels, animated and live-action films, and a Scottish indie pop band that takes its name from the story. The franchise encompasses multiple adaptations across different media, including live-action films in France and animated series in Japan and Canada, all centered on the adventures of the boy and his dog.
Belle and Sebastian is set high in the snowy Alps during the Second World War. The resourceful Sebastian is a lonely boy who tames and befriends a giant, wild mountain dog, Belle – even though the villagers believe her to be ‘the beast’ that has been killing their sheep.
September, 1945. Sebastian impatiently waits for the return of his friend Angelina, whom he has not seen for two years. When the plane carrying the young woman to her small village in the Alps is reported to have crashed in the mountains, Sebastian is convinced that Angelina is still alive. Along with his faithful dog Belle, Sebastian embarks on the most dangerous adventure of his life.
12 year-old Sebastian has decided not to follow his father and Angelina to Canada, deciding to stay in the alps to watch over Belle who has now become the mother of three beautiful pups. When a stranger arrives claiming to be Belle’s rightful owner, Sebastian will do all it takes to protect his best friend and her little ones.
10-year-old Sebastien reluctantly spends his vacation in the mountains with his grandmother and aunt. Helping them with the sheep is hardly an exciting prospect for a city boy like him - but that is without considering his encounter with Belle, a huge dog mistreated by her owner. Ready to do anything to fight injustice and to protect his new-found friend, Sebastien will spend the craziest summer of his life.
