Lisbeth Salander, a computer genius, does not hesitate in front of anything in order to achieve her goal. She does not forget and does not forgive, and when she encounters corruption and abuse, especially against women, she is ruthless.

She declares war on those who pull the strings of the flesh trade industry, using her skills as a hacker to assist in the investigation initiated by her friend Mikael Blomkvist, editor of Millennium magazine. However, she inadvertently gets involved in a double murder while the police are chasing her for a third murder. All the evidence incriminates her and her fingerprints have been found on the weapon of the crime. As all forces in Sweden and determined criminals are on her trail, Lisbeth has no other choice: she must find and reveal the truth before it is too late for her own life.
