A teenage boy from a working-class Parisian suburb is sent to live with his wealthy relatives in the affluent neighbourhood of Neuilly-sur-Seine, where he struggles to adapt to their privileged lifestyle and snobbish attitudes. The culture clash between his background and their world generates both comedy and friction, as he tries to find his footing in an environment utterly foreign to him. The film is a sequel continuing the fish-out-of-water story established in the original.
