The film is reminiscent of "Gosciminska" by virtue of both analogy and a reversal. Both films are based on a written text - a colloquially worded document written and read out by the protagonist, which initially takes form of curriculum vitae, but as it progresses begins to sound more like a letter of complaint. The protagonist's account spans from the pre-war to the post-war period. What is reversed is the relationship accounts and the film footage illustrating them. The unique method of editing archive material is particularly worthy of note. As each take is replayed a number of times the footage looses its credibility.
