The ten one-hour Dekalog films are set around the same modern Warsaw apartment building. Each film deals with a theme - love, marriage, infidelity, parenthood, guilt, faith, compassion - exploring the relevance of one of the Ten Commandments, showing how people deal with moral dilemma in their everyday lives. The soundtrack for nine of the ten Dekalog films marks the point where the creative relationship and friendship between Preisner and Kieslowski first flowered and contains the seeds of much of Preisner's later work. (Kieslowski and Preisner decided that Dekalog X would not require an original music score). The music was recorded by Zbigniew Malecki and Aleksander Dowsilas at Radiowy Dom Sztuki Studio, Katowice.
