In BIRTHDAY GIRL, shy bank teller John (Ben Chaplin) orders his Russian bride from an internet site. The good news is Nadia (Nicole Kidman) is beautiful. The bad news is that she does not speak English, she smokes, and on the way home from the airport she has to throw up. John has second thoughts, but can't get anyone from the agency on the phone. Meanwhile, Nadia efficiently discovers his stash of porn and even more efficiently makes herself sexually indispensible. Nadia stays at home and knits, and John goes off to the bank with a spring in his step and the ring she brought him on his finger. But Nadia’s birthday celebration is interrupted by the arrival of her cousin and his friend. At this point, things start to go wrong, including betrayals, a bank robbery, a lot of smacking around and threats with guns.
