Pun Salad

This is (in case you've been cut off from civilization for a few years) the movie version of the sequel to The Girl With the Dragon Tattoo. Some sequels stand on their own, but you'll really want to have (at least) seen the previous movie in order to understand what's going on here.

The titular Girl, Lisbeth Salander, is basking in the sunny Caribbean when warning cyberbells go off: one of the villains from the previous movie is behaving badly. So it's back to dreary Sweden for her. Meanwhile, her co-hero from the previous book, crusading journalist Mikael Blomkvist, is managing an exposé of the Swedish sex-exploitation trade in which the kinks and perversions of numerous Swedish bigwigs in business and government are to be revealed.

Almost immediately, a number of people involved are murdered, and Lisbeth is framed. Both she and Mikael work independently to find the true culprits. Along the way, revelations are made about Lisbeth's past history.

It's not for the kids. (MPAA: "brutal violence including a rape, some strong sexual content, nudity and language.") And—hope you won't consider this a spoiler—the ending is pretty much a cliffhanger for the next installment.
