Anke is disappointed. After her last day of work in a parish office in the Black Forest, she was looking forward to a summer holiday together with her children on the Baltic coast, a place where they lived as a young family and where Anke spent her best years. But her son Max, who lives in Hong Kong, cancels at short notice because the pro-democracy protests in the city have brought life there to a standstill. In the emptiness of her retirement, alone between four walls, Anke decides to fly to Hong Kong to see her son. While Max is away on a business trip, she takes up residence in his flat and cautiously begins to navigate this mysterious new world.
