Siggi Arnold, multiple co-owner of an apartment building, made a fatal fatal down the staircase, and was pushed. The co-habitation wasn't nearly as idyllic as it seemed, especially after objections to his plan to take in Syrian refugee families in his empty units, especially from nagging rule-stickler pensioned co-owner Alma Meyer, whose nephew, early-retired alcoholic Hans-Peter Götz, hides with her help moon-shining in the cellar. Tenant Cosima Berger, a social worker, was womanizer Siggi's jealous lover. Recently-notice-given tenant Lars Mäule enjoys a suspiciously lavish lifestyle, without a job, actually as illicit tantra-masseur and 'life coach'. Alma Meyer makes a non-fatal fall down the staircase, during a fight between Hans-Peter and Lars.
