Despite her terminal illness, 22-year-old Lea travels to Zurich. After years of suffering, she has decided to depart from life with the help of an organization offering suicide assistance. She sends a text message to her sister Rita, her overwhelmed mother Hannah and her grandmother Maria asking them to come and see her. She would like to spend her very last day, her own birthday, with her family. Lea’s ex-boyfriend Heiner also finds out about her plans and travels to Zurich. In her guest house Lea also meets weird but likeable Moritz who has come to Zurich for the same reason as she.

In Zurich parallel worlds collide: Lea’s mind is made up, but she encounters fierce resistance from her own inner circle of loved ones.
