Synopsis: "I don’t remember when I first found out — that all people will die. But I think I was very young then." - Tilia, 8 years old. Tilia’s thoughts on life and death take her on a journey through her imagination. The journey leads her from the underworld up to the heavens, where people travel by flying trains while deciding when they want to return to Earth — and whether they want to be a boy or a girl in their new life.
