When the police reveal a narcotic smuggling the driver is shot dead. It appears that the driver is Superintendent Martin Beck's son. Beck breaks down and moves out of the way. But on his colleagues request he returns.

An Asian woman is found dead in the water of Stockholm's archipelago. She has been murdered and everything indicates that she was a prostitute. Meanwhile a series of break-ins has occurred on an island outside of Stockholm. Suddenly a retired old man is also found dead in his own yard. Now Beck has two cases to solve and they both point in the same direction.

In this film Beck and his team are trying to find a serial killer, whose victims are spread all over Sweden. An obvious connection is that all the victims are women, and they were all in the same class, and Beck thinks that a scandal back in the past has something to do with the murders. But no one wants to talk about the past and it becomes a struggle to find the perpetrator before the final murder - only one woman is still alive.
