The second film expanded from the "Thou Shalt Not Commit Adultery" episode of Krzysztof Kieslowski's ten-part TV series Dekalog, this tale of a young postal worker who spies on a sexy older woman in the flat opposite is surprisingly subtle and heartfelt rather than sleazy and voyeuristic.
As the power shifts between the watcher and his subject, between romantic love and carnal lust, Kieslowski taps into the most intimate, fragile areas of human relationships with gripping and often suprisingly humourous results.
