Dr. Modersen died from an intravenous overdose of self-medicated vitamins against cell aging. Last known visitor was courier Timo Rüttgers, who bitterly blames Modersen for reporting him so as to end his health practitioner license. Patient Wolf Jürgens, a lab employee, believes Modersen's persistent false diagnoses prevented a therapy that might have prevented him becoming terminal. The team also looks into fresh widow Stefanie, who started an affair with therapist and family friend Christian Kolditz, and pre-teen son Jonas, a gifted pianist. Neither ever got over the suicide by drowning of firstborn swimming champion Max, resulting from the tyrannical father's impossible expectations.
