Peter, a journalist from Hungary, notices a man who looks like his long-disappeared father in a documentary film. He escaped Communist Hungary in the 1970s and nobody has heard of him since. Peter travels to the USA to find him. The series of events leads to the revelation of secret research on voices from space. One of Hungary's most distinctive directors, György Pálfi, refers to a book by the icon of Polish sci-fi Stanislav Lem.
