Bloody Boys follows three families through three parallel stories.

Susan is longing for her boyfriend Anders who is away on business. Isolated in the flat they recently moved into, she has got the feeling that someone is visiting the apartment during night-time, and she has nightmares about living in the streets searching for Anders who has left her behind.

A worker takes time off from the post office to become a crime writer, but he is disturbed by a workmate who always seems to have some reason to visit his little cabin.

Sandra, a young female student, rents a room from Anna-Lisa, a middle aged actress and former ballet dancer in Berlin.

Johan Falk hasn't been working for over a year since he resigned from the police. Most of all he wants to move out to the countryside, but fate has a different thought.

A mysterious woman named Grace hides in a small mountain town from criminals who pursue her. The town is two-faced and offers to harbor Grace as long as she can make it worth their effort, so Grace works hard under the employ of various townspeople to win their favor. Tensions flare, however, and Grace's status as a helpless outsider provokes vicious contempt and abuse from the citizens of Dogville.
