"Je t′aime, Chérie." These three words and a Bulgarian volleyball jersey is all Martina, a young working woman from Berlin, is left with after a night at the beach spent with a mysterious lover. But then she learns that she is pregnant, and once the baby is born, she starts for Bulgaria to search for her son′s father. The orderly yet diffident Thomas, an employee of the embassy of the GDR, joins her in order to provide diplomatic support. The quest, however, turns out to be rather difficult. After some failures, the odyssey ends at the wedding of a member of the national volleyball team. Martina is convinced that she has finally found the father of her child and presents the jersey as evidence. But the man has to disappoint her: Subsequent to the indicated game, he had switched jerseys with a player from the GDR! Thus, the father must be found in Martina′s homeland.
