The invention of the wheel

A caregiver in a nursing home lifts the mobility-impaired resident Danijel Filipovic into the bathtub, but leaves him alone briefly—upon his return, he finds Filipovic drowned. Detectives Moritz Eisner and Bibi Fellner investigate in an environment of overwork, understaffing, and interpersonal tensions. Motives are not immediately obvious, but family conflicts and a strained relationship with the nursing staff come into focus.
