JUST BETWEEN US (2010)

Nikola is a man who knows how to really enjoy life; he's even able to rouse sympathy for his sinful ways. His brother turns a blind eye to his philandering although, with a broken marriage behind him, he doesn't have a clear conscience, either. Is there anything positive to be said about infidelity, or does it simply deserve the utmost contempt, particularly when it's more premeditated than spontaneous?
