Set in 1931 in Paris, France, the story revolves around a 12 year old orphan named Hugo Cabret who lives in a Paris train station working as the clocks' timekeeper in his Uncles absence. He is a recluse, and for good reason, but comes in contact with a toy seller and his goddaughter, named Isabelle. This chance meeting changes everything.
Before Hugo's father died, he discovered an old, broken automaton in the attic of a museum he works at. His father tries to fix it but with his death in a fire, the automaton is left. Hugo tries to fix the automaton by following the instructions left in his fathers notebook. But during a run-in with the toy seller, Hugo loses his treasured notebook. Now he must find a way to mend the broken wind-up toy using his own logic. Once in working order, the automaton reveals a secret that will change his, and the toy seller's, life forever.
