Christopher Nolan

Life is just not quite as smooth as it was for Will Dormer, a Los Angeles detective, as he gets caught up in an internal affairs problem that could doom his career and is then sent to Alaska to investigate the murder of Kay Connel where he is plagued by insomnia. In the pursuit of trapping the murderer at the crime scene, he accidentally shoots his partner, Eckhart, who could have been a possible witness against him in the internal affairs problem. He soon receives threatening phone calls from Kay’s murderer who attempts to snap a deal with the detective to get away freely so as to keep mum about the ‘accidental’ killing. The movie keeps us guessing about whether he succumbs to the threat or fights back.
