At the beginning of a sunny spring, the world of three-time family father Ulrich Wigand is thrown into turmoil: the diagnosis of a terminal brain tumor gives his only son Yannick just three to six months to live. The desperate fight for the life of the four-year-old becomes an odyssey through the world of healers, Eastern and alternative medicine, and the starting point for intense struggles between father and son, which threaten to tear the family apart. But intimacy and closeness also develop between the father and his son, who often expresses wisdom and a deep understanding of his path in his clear and imaginative language, impressing many people with his charisma, even as he loses more and more of his abilities: walking, speech, gesture, facial expression, and ultimately any ability to move. Disturbing, mysterious things happen. Coincidences? We'll see.
