Mystic River is an old masterpiece. I had watched it when it first came out, and while I remembered it “was a good movie,” I had forgotten what it was about.

Sean Penn won an Oscar for best actor in a leading role, and Tim Robbins for best actor in a supporting role.

The story is about three friends from a rough neighborhood in Boston who were best friends as boys. Jimmy Marcus (Sean Penn) was an ex-convict when his daughter Katie was murdered. His friend Dave (Tim Robbins), a blue-collar worker, saw Katie last, making a fool of herself late at night, dancing on the bar in a local watering hole. His other friend was Sean (Kevin Bacon), who happened to be a homicide detective, and he was put on the case. As the three childhood friends deal with this tragedy each in their own way, events unfold that pit them against each other.

There is a backstory, which is woven into the main plot. It turns out that Dave was abducted by child molesters one afternoon in the summer of 1975, when the three boys played in the streets. After days of sexual abuse he escaped and returned, but things were never quite the same for the three friends. The demons of the summer of 1975 come to haunt all three of them when Jimmy’s daughter was killed.
