A woman is found murdered in the middle of the Øresund Bridge – right on the border between Sweden and Denmark. The Swedish and Danish police are called to the scene. What at first looks like one murder, turns out to be two. The bodies have been brutally cut in half at the waist and put together to form a single corpse. This spectacular double murder is just the beginning of a wave of violence the like of which no one has ever seen before. The Swedish and Danish police find themselves in a race against the clock in a deadly showdown with a superior enemy, where no one will be the same when it’s over.
