To see snow and learn German, the young Vietnamese girl Trúc Lâm (Nano Nguyen) moves to a small town in the middle of the Erzgebirge mountains in Saxony. She is fascinated by the forest, the mountains and the clear air that smells of clouds and winter and burns her nose when she breathes it in - for which she is mocked by her classmates. On a trip to a mine, she gets lost in the labyrinth of dark shafts and suddenly emerges on the other side of the mountain. This world is almost identical to the old one - but the characters have been replaced. In the town on the other side, she meets Duc (Tri An Bui), the son of a Vietnamese family who run an Asian snack bar. And while Duc tries to find a balance between his German-Vietnamese heritage and the expectations of others, Trúc Lâm accepts the help of a ghost to find her way back into her world.
