 Graham, an annoying, nerdy guy, and his adopted brother Allen, who now insists on calling himself Rex, arrive in France because their great-uncle died and left a mansion to them. But the staff at the mansion is unprepared for their arrival; Graham s limited French skills meant he didn t realize that the repetition of "C est qui?" on their phone call meant they were asking who he was, and instead thought they would be bringing a key when they met him. Graham s overreaching his French abilities bring continued complications; meanwhile, both brothers find themselves falling for the winsome Isabelle, daughter of the butler, Jean, and mother of a small boy. And when the brothers try to sell the mansion, the staff reveals more of their skills to prevent the sale.
