Based on the bestselling novel by Stieg Larsson, it tells the story of a disgraced financial journalist, Blomkvist, and a tattooed, severely antisocial computer hacker, Salander, who are hired to look into the disappearance of a girl, Harriet Vanger, who vanished 40 years previously. The uncle who hired them is convinced his niece was murdered by a member of his own dysfunctional family, and as the pair link her disappearance to a number of other grotesque murders that took place at the time, they begin to unravel a dark and appalling family history. But the Vanger's are a secretive clan, and Blomkvist and Salander are about to find out just how far they are prepared to go to protect themselves.
