Constanze and Jens are a team, a couple, parents, but above all they are one thing: hard working people. Between night taxi rides and weekend shifts at the office, they just about keep their lives going, meeting for short conversations in Jens' taxi and driving their son Luis back and forth. Until one day a phone call from school upsets their routine: Luis is being bullied. The reason is his beloved unicorn backpack. The school headmaster advises the parents to buy a new one, which creates a deep conflict in the couple. Should Luis conform or impose himself, even if it means catching attention? The situation escalates and the taxi becomes a kind of boxing ring, a microcosm in which the parents fight over universal issues. Constanze and Jens want to do right by their son, but can only fall back on quick fixes instead of really being there for him.The pressure of everyday life is too great, the time they can devote to each other is too little. While Luis continues to be humiliated and beaten at school and eventually turns from victim to perpetrator, the couple's relationship threatens to collapse in a spiral of accusations, feelings of guilt and helpless attempts to protect their son.
