Everything in architect Tom Pohlmann's life is optimized down to the last detail. He even works on his weakness, his panic fear of speaking in front of people, with the help of a psychology app - in parallel to his morning sports program. Sarah Wünsche's chaotic everyday life feels completely different: she is raising her twelve-year-old son Paul alone, working night shifts and fighting for a mini-loan to get her bankrupt kiosk back. In order for two such contrasting people to come closer together, chance has to come into play several times: first in a minor hit-and-run accident that almost lands Pohlmann in prison; and then in the children's ward at the hospital, where the notorious speeding driver is doing his community service. There he meets Sarah's son Paul, who is suffering from mysterious breathing difficulties.
