I, Cesar (2003)

Cesar is a young schoolboy living in Paris with his family. Their life is ordinary, but Cesar wants more excitement (which he creates, in one instance, by claiming to his teachers that his father has been arrested). During the school holidays, Cesar and his friend Sarah decide to help their mutual friend, Morgan, find his father who supposedly lives in London. Each one tells their parents that they’re staying with the other two, and together they sneak out to begin their search.
