Orphaned and alone except for an uncle, Hugo Cabret 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. Accompanied by the goddaughter of an embittered toy merchant, Hugo embarks on a quest to solve the mystery of the automaton and find a place he can call home.
Terry is a small-time car dealer trying to leave his shady past behind and start a family. Martine is a beautiful model from Terry's old neighbourhood who knows that Terry is no angel. When Martine proposes a foolproof plan to rob a bank, Terry recognises the danger but realises this may be the opportunity of a lifetime. As the resourceful band of thieves burrows its way into a safe-deposit vault at a Lloyds Bank, they quickly realise that, besides millions in riches, the boxes also contain secrets that implicate everyone from London's most notorious underworld gangsters to powerful government figures, and even the Royal Family. Although the heist makes headlines throughout Britain for several days, a government gag order eventually brings all reporting of the case to an immediate halt.
