Disgraced journalist Mikael Blomkvist (Daniel Craig) accepts an invitation to surreptitiously investigate a fourty year old unsolved murder on behalf of the victim's uncle, Swedish industrialist Henrik Vanger (Christopher Plummer). Meanwhile, tattooed hacker Lisbeth Salander (Rooney Mara), hired to investigate Blomkvist, discovers the truth behind the conspiracy that led to his fall from grace. Thrown together by fate, the unlikely duo uncovers a secret history of murder and sexual abuse festering beneath the veneer of Sweden's industrial past, all the while drawing closer to a quiet evil waiting to engulf them both.
