Sinopsis
To experience snow and learn German, the young Vietnamese woman Trúc Lâm moves to a little town in the Erz Mountains. During a guided tour of a mine, she leaves her group and reaches the other side of the mountain through a secondary shaft. The world there is similar to the one she left – only all the people are different. She meets Duc, who is also from Vietnam and whose parents have an Asian snack bar. And she meets a mysterious spirit who offers to make a deal with her to enable her return to her old world.
