In this Dickensian fable, two German orphans - 12 year-old Prosper (Aaron Johnson) and 5-year-old Boniface (Jasper Harris), nicknamed Bo- flee Hamburg for Italy, when their awful Aunt Esther and Uncle Max only want to adopt little Bo, but not his big brother. Determined to stay together, Prosper and Bo make their way to Venice, a city their mother had always described as a magical place. There, they become members of an unlikely gang of pickpockets under the direction of the elusive ''Thief Lord,'' an outgoing 15-year-old named Scipio (Rollo Weeks). Prosper and Bo delight in being part of this colourful new ''family,'' which takes up residence in an abandoned movie theatre. Propelled on a fantastical adventure, Prosper and Bo make a discovery that will change the course of their destinies forever in the heart-warming family film The Thief Lord.
