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.

Through previously undiscovered private letters, photos and diaries that were found in the Himmler family house in 1945, the "The Decent One" exposes a unique and at times uncomfortable access to the life and mind of the merciless "Architect of the Final Solution" Heinrich Himmler.
