Un étudiant est engagé pour devenir le précepteur d'un élève singulier: un jeune garçon vivant à l'intérieur d'un bunker, isolé du reste du monde.

Four former classmates, Philipp, Leonie, Timo and Yasmin arrange reunion over the weekend in one of Philipp's properties. Philipp's wife and daughter are also present. The weekend ends in bloodbath however, with three people dead and the suspect in coma. Two years later Leonie's mother asks the former classmate of the alleged murderer, Doro Kagel, to reopen the case. She would never trust her daughter to do such an act, and even Doro starts having doubts that are only reinforced by the silence of the survivors.

Mia, who lends her voice to a Japanese Anime super heroine, finds reality and fiction to be interlacing more and more. Suddenly, Mia can see electricity, leap off rooftops and save people’s lives. But as Mia’s superpowers grow, so does her awareness of looming danger. Just as in the Kimiko anime, hostile powers are planning a massive electric blackout to destroy the city, maybe even humanity itself. And while Mia tries to save everybody from the imminent crisis, it's her own stability which seems to be put at stake.
