The family of 14-year-old Lea is part of a cosmic group that believes in an origin of humanity on Jupiter. Due to a disability, Lea’s brother, Paul, is unable to communicate, and this has driven the family to the obscure cult that promises salvation in a higher existence on Jupiter.

The sect plans a collective suicide, by which their souls are supposed to reach Jupiter, in the course of an outing into the mountains. Here, for the first time, Lea rebels against her parents’ control and desperately tries to dissuade her family from this plan. However, the prospect of finally being able to communicate with their son on Jupiter, her parents’ are not open to conviction. Lea faces the dilemma of whether to follow them or to forge her own path on Earth.

While searching for herself and in defining her own values, she learns to stand up for herself and recognize true friendship. In the end, Lea takes her decision: she plans to stay on Earth and embrace life with all its challenges.
