London, 1850s. After five years in an Australian penal colony, the Artful Dodger returns to London in search of a hidden fortune. Unaware of the fate that befell Twist, Fagin and Sikes, Dodger revisits the criminal underworld of Dickensian London to seek out his old comrades, any of whom might possess the key to the treasure. He finds the city a changed place from his youth: with law and order upheld by a new police force, Fagin gone to the gallows, his old gang scattered and danger around every corner.
