Reporter Sebastian Waldheimer, in a weird suit and helmet, was fatally hut by a car and left in front of a supermarket. Working on articles about the elderly, he tried out a borrowed 'Age-Explorer' suit from seniors home "Sonnenberg", where it helps staff to grasp the residents' physical experience. Korbinian Hofer and constable Michi Mohr notice the damaged car of the home's own physician, Dr. Arthur Passauer, who denies a recent accident and turns out an uncle of "Times Square" publican Jo Caspar, whom he gives a free checkup there. Sebastian frequently called home manager Cornelia Wesslinger, whose popular right hand and boyfriend Ludger Mollenhauer whispers Passauer and Waldheimer bickered about old letters, which Jo is asked to remove, too late. But there's also inconspicuous fraud. Meanwhile the precinct buzzes with rumors since absent detective Christian Lind and controller Patrizia Ortmann didn't return together from a Munich course.
