A mysterious phone call puts Kluftinger and his colleagues Maier and Hefele on the trail of a brutal series of murders. A serial killer who cuts out the hearts of his victims and drapes them macabrely at the crime scene is up to mischief in the Allgäu. There is hardly any time for Kluftinger's own worries, the chest pains that are making his life hell.
