Melanie is in her mid-thirties and works for the Brandenburg police. Her precinct is the province north of Berlin. Melanie likes it when anybody likes her. If it gets political, she keeps herself out. But that's no longer so easy when her best friend Lydia, an ex-daily soap star, makes herself important as a populist influencer with right-wing slogans in her home village and a street disappears overnight. Its bumpy cobblestones were the last evidence of a dark time when building material for the Wehrmacht was mined at the Kiessee, today a bathing area. Forced laborers and concentration camp prisoners toiled here. Elementary school teacher Anja considers it a thoughtless mess that this stone memorial to history should simply be asphalted. With brown homeland paroles, Lydia heats up the mood in the village and earns good money through clicks on the Internet. When the violence escalates, law enforcement officer Melanie, who is addicted to harmony, has to decide which side she is on.

Grandpa Oskar takes neither the truth nor himself very seriously. The rascal has just been released from prison, where he was serving a sentence for imposture. Since the ex-con needs a place to stay, he quartered himself in the old construction trailer in the farthest corner of the garden of his daughter Tilda, who is still mad at him. The senior soon meets his autistic granddaughter Fanny, whose antics and peculiarities threaten to break the family under. In contrast to the old man, the 8-year-old takes the truth very seriously. In order to gain their trust, Oskar does not introduce himself to the comic-loving girl as the criminal grandpa, who has been missing for years, but as Professor Krypton. For Fanny, who prefers to wear a brightly colored superhero costume and is teased at school for it, the omniscient mentor from the Superman planet comes along just at the right time, because she has a dream: To win the talent competition at school!
