Sabine Kaiser has to do a friend a favor: Her heavily pregnant friend Elke Becker has had a falling-out with her husband and, without further ado, has banished him from their bedroom. Although the police superintendent is extremely busy, she accompanies Elke to a routine checkup at the clinic of the renowned reproductive medicine specialist Dr. Alexander Hecht.

Elke became pregnant through in vitro fertilization, and her due date has long since passed. Upon arriving at the clinic, hormone-ravaged Elke, of all people, makes a gruesome discovery: Dr. Hecht is lying dead in a dumpster!
