Some cops are killers, a robbery can be a kidnapping in disguise, and a friend may turn out to be an enemy after all. Peter Lindmark does wonders when he gets to work with his own script, rather than the novel he used as the basis for his most recent movie, "Exit". While "Exit" is as complicated as it is predictable, "Rånarna" tells a simple story that is full of surprises. There seems to be no bottom as grand larceny investigator Karla Arvidsson (Sofia Helin) is sucked deeper and deeper into her current case, a series of highly professional bank robberies rooted in paramilitary right-wing underground circles. Much as the movie owes to the clever script, it's Sofia Helin's personal touch that makes you want to know what happens next. She makes Karla come alive as a rich character, with a story of her own that extends well beyond the two hour window of the movie. No doubt she will stay with you for a while. Go see it if you liked 2001's "The Pledge".
