In the apartment building where the twins Nikosch and Nini live something is always going on. Everyone knows each other, kids grow up together. But from one day to the next, all doors stay closed; contact with other people is now too dangerous, because of this virus. The children are no longer allowed to play with each other, nor to go outside or to school… and to them, this feels like they are stuck in eternity. Bit by bit, the apartments become too cramped, and tensions rise, because everyday life is too stressful. But in the middle of this unnerving boredom, the twins notice something: In the fancy house on the opposite side of the street a torchlight flashes at night. Again and again. A morse code: SOS!
