John Adams is a US embassy chargé d'affaires in a communist country in Eastern Europe.

One day he has to deal with a very special case: in the front yard of the embassy, a baby has been laid down, as if it had "fallen from heaven"!

Sonja Novaswobida, as she is called, is also supposed to collect further information on site on behalf of her government.

Due to mutual distrust, the men's relationships with the Eastern European state employee initially range from difficult to cold, especially since Kovacs turns out to be a particularly tough opponent for Ambassador Adams.

Adams, however, wants to hand over just that, and instead, with some ironic ulterior motive, gives Adams another find that someone had thrown over the embassy's bridle: a supposedly ingenious, modern musical score that Kovacs plays the piano reluctantly at first, but then enthusiastically after realizing it must, how little the Americans can do with such modern music.
