Orphaned and alone except for an uncle, Hugo Cabret (Asa Butterfield) lives in the walls of a train station in 1930s Paris. Hugo's job is to oil and maintain the station's clocks, but to him, his more important task is to protect a broken automaton and notebook left to him by his late father (Jude Law) . Accompanied by the goddaughter (Chloe Grace Moretz) of an embittered toy merchant (Ben Kingsley), Hugo embarks on a quest to solve the mystery of the automaton and find a place he can call home.
