 A young American couple is murdered while vacationing in Europe. The young woman’s father Jacob Kanon, a New York City police investigator travels to Europe to hunt down the murderer. Other young couples in France, Germany, Denmark and Sweden have since then been killed and the evidence points in the same direction. Kanon joins up with Scandinavian journalist Dessie Larsson to find the murderer. Kanon and Larsson must work against time since every murder is preceded by a postcard to a regional daily.
