David Cronenberg's new movie 'Eastern Promises' is a tale from the grim and very violent world of the Russian Mafia. Set in London, the story begins with the birth of a baby and the death of her 14-year-old mother. It stars Naomi Watts as Anna, a midwife who finds the dead mother's diary, and Viggo Mortensen, as a driver for the Russian gangsters whose name show up rather a lot in the diary. But because it's all written in Russian, Anna is initially unaware of what she has stumbled into.
