Fiona Platt (Claudia Michelsen), 42, has everything a woman desires: She is a successful Marketing-Expert in a big ad-agency. She has a handsome, renown architect as her husband, Ben (Stephan Kampwirth), 42, two beautiful, healthy daughters, Paulette (Luise Aschenbrenner), 15, and Lina (Laura Kirsch), 8, and a politically active mother, Gitta (Maren Kroymann), 63, who takes care of the household and the children. Fiona's busy schedule doesn't allow her much quality-family-fun-time, so her understanding, attentive husband jumps in whenever help is needed. Everything seems to be perfect. But then Fiona finds out who the father of the baby of nine-months pregnant, attractive, lively 26-year-old rock-singer and neighbor, Julia (Birte Hanusrichter) is: Ben. Although the parents-to-be assure that it was "just" a one-night-stand and that they have no feelings for each other whatsoever, the situation still threatens to upend the life of the always so controlled Fiona. Eventually she decides that divorce is a no go. She wants the opposit instead. Being such a pragmatic and rational Marketing-Executive, Fiona develops an - almost - perfect "Happy-Family-Plan." And it seems to work with huge success - just not for Fiona. She can't keep up with young, fun Julia who Fiona's daughters love so much while she has to stay focused on the ad-agency's pivotal pitch to win Tracon as their new account.

A series of ritual murders shakes Hamburg. First a songwriter is stabbed and scalped, then a scientist. Investigations by Kriminalhauptkommissar Jan Fabel lead into the left student scene of the 1980s. Both victims belonged to the environment of the terrorist Franz Mühlhaus, who was shot during a police operation. His followers could then start a new life. It quickly becomes clear: the key to the current murders lies in the case at the time.
