12 years ago, Rolf suffered a violent accident that caused him severe amnesia. During his long rehabilitation, Rolf had to rebuild his identity from scratch and, while doing so, he invented a flying machine that would give him the freedom of a bird. In a very intimate following of a four year period we discover Rolf´s way of perceiving the world and the contradictions of a character who suffers at discovering that he has fathered two girls and that he has to make up his mind either at becoming an adult or persuing his life long dream of the flying machine.
