Perry (Ewan McGregor) is a lecturer at Oxford University, respected by students and colleagues. Together with his girlfriend Gail (Naomie Harris), the two went to Antigua, where they were going to spend a romantic and long vacation. In Antigua, Perry met a man named Dima (Stellan Skarsgård), and the two people with similar interests quickly formed a friendship. In fact, Dima's true identity is a millionaire from Russia. He participated in the money laundering activities of Russian criminal organizations and is a money laundering expert. However, after a long immersion in such a dangerous industry, Dima felt physically and mentally exhausted. He hoped that Perry could help him apply for political asylum from the British intelligence agency.
