Stealing Lives [HWChil] - Don't Miss
Fact-based drama examining the growing problem of identity fraud -
one of Britain's fastest growing crimes - revealing how a group of
young Nigerian men, living in the UK for over 10 years, set up a
complex multi-million pound scam involving stealing the identities of
dozens of people. By opening up hundreds of bank and building society
accounts in the victims' names they withdrew the most money possible,
leaving the victims with a legacy of bad debt.

To explore this growing problem, Stealing Lives tells the story of a
police investigation into a trail of shattered lives and defrauded
banks which led to a gang of compulsively driven young men, and a
young policewoman from Essex who spent two years doggedly pursuing a
case against them. The clever, charming leader of the gang first
laughingly dismissed her and then threatened her to breaking point.

Behind the drama lie the fundamental aspects of identity. From the
anonymous IT statistics we've all become on the screens of big
institutions, to the culture-clash between economically excluded
African nations and the exploitable debt-culture of the West. Through
the details of this extraordinary case, the film questions how we
define ourselves and what makes us who we are.

The film reveals how the scam was perpetrated and explores the
motivations that led the offenders to commit such an audacious crime.
Events are based on actual incidents recorded on police statements
and court records.
