Desc: Liczba doskonala: Directed by Krzysztof Zanussi. With Andrzej Seweryn, Jan Marczewski, Julia Latosinska, Jan Nowicki. What makes life meaningful: success or love? This dilemma is faced by Joachim, a fulfilled man approaching the end of his life, and a young mathematical genius, David. This film is a return to the central themes of the director's work. The answers he gives this time are perverse and not obvious.
