Inspector Rivera and his team are called to the scene of what appears to be a suicide. Apparently, a member of White Brotherhood, a neo-Nazi movement, has jumped off an eight-storey building. But suspicion is raised about the suicide theory as the investigation links the case to similar deaths a few years before.

Inspector Rivera's former girlfriend, Sara, rings him seeking help. She's seen her partner Francesco hanging from a tree in her garden. But when Rivera arrives, the body isn't there, and his team begins to raise doubts about Sara's state of mind. A reappearance by Francesco causes Sara to question her own sanity.
