In a small harbor town in France, an elderly shoeshiner named Marcel leads a modest, content life with his wife Arletty. They live in a tight-knit community where everyone knows and helps each other. One day, Marcel encounters an African boy named Idrissa hiding in the docks. The boy is a refugee, illegally trying to reach his mother in London. Despite his own limited means, Marcel decides to shelter Idrissa and hide him from the authorities. As he navigates through bureaucratic obstacles and the prying eyes of Inspector Monet, Marcel enlists help from his neighbors and friends, showcasing the spirit of solidarity in their community.

Marcel's determination to protect Idrissa becomes increasingly challenging as the police tighten their search. His wife’s health deteriorates, adding to his worries and testing his resolve. Despite all difficulties, the community’s collective effort turns into a beacon of hope. The story builds a strong emotional narrative around themes of compassion, resilience, and human connection as they collectively defy law enforcement to ensure Idrissa's safety.
