Strewn bones are found belonging to ruthless SS-officer Alfred Döberitz, missing since 2002, wrongly assumed to have returned to his South American hiding pace. State attorney Brehm showed exceptional zeal to prosecute him, barrister Erich Fehling to assure his defense, in the matter of a 1944 bloodbath among civilians in Nazi-occupied Italy. Forensic doc Julia Löwe, who is fluent in Italian, travels to the intended key witness, sole survivor Anna Rivolta, who is far from cooperative. Henrik Mertens, still looking for the mole in his team, also grills her adult grandson in Berlin, Franco Rivolta, and Döberitz's surviving subaltern Erich Fehling. Löwe learns about Mertens despair to raise the ransom for Dr. Katrin Stoll and volunteers to stay on as her replacement, now indefinitely.
