Krotki film o milosci (A Short Film About Love) (1988) - Krzysztof Kieslowski
19-year-old Tomek whiles away his lonely life by spying on his opposite neighbour Magda through binoculars. She's an artist in her mid-thirties, and appears to have everything - not least a constant stream of men at her beck and call. But when the two finally meet, they discover that they have a lot more in common than appeared at first sight... Tomek, a young post office worker, is obsessed with Magda, the promiscuous woman who lives in the tower block opposite. He spies on her through a telescope and finally declares his love. She initiates him into the basic fact of life - there is no love, only sex. Tomek, shattered, tries to commit suicide but doesn't succeed. When he returns from hospital, it is Magda who becomes obsessed with him.
