Insomnia

Crime drama following detective Jonas Engström (Stellan Skarsgard) who has been sent to the Arctic circle to investigate a recent murder. When there, he finds himself unable to sleep due to the perpetual daylight. The situation gets worse for the respected cop, however, when he fouls up an opportunity to catch the murderer and, hidden from view, accidentally shoots dead his partner instead.

Engström then tries to save his reputation by pinning the killing on the villain; however, the villain is the one person who saw what actually happened and he soon uses this knowledge against the cop, drawing him into a subtle and dangerous game in which their two fates become inextricably intertwined.
