Twelve-year-old Tomy spends the summer of the 1999 solar eclipse with his best friend Chris on an alpine pasture. When Chris learns that Tomy's father is in hospital with AIDS, their friendship falls apart – and Tomy suddenly finds himself torn between exclusion and the secrecy of his own family.

When 12-year-old Karli moves to an old hotel in the Alps, he discovers an elevator that harbors a secret – it’s a magical time portal that transports him back to 1938! There, he befriends Hannah, a spirited Jewish girl, and Georg, a shoeshine boy. But when Georg is falsely accused of stealing, the children must solve a mystery case hidden within the hotel’s walls, all while the shadow of Nazi Germany begins to grow around them.
