Simultaneously on the business front, Will's and his partner Sandy's (Martin Freeman) state-of-the-art offices in the Kings Cross area are repeatedly burgled by a group of Slavic-language-speaking thieves. The thieves employ a 15-year-old traceur named Mirsad "Miro" (Rafi Gavron) whose acrobatic skills allow them to enter the building. Miro is actually a refugee from Bosnia and Herzegovina living with his Bosnian Muslim mother Amira (Juliette Binoche) who works as a seamstress, while his Serbian father got murdered during the war.
