Eventually, this episode from the DEKALOG series will take on a life of its own. Beginning with a melodramatic premise-- a successful young doctor afflicted with irremediable impotence instructs his loving wife to take a lover-- Kieslowski constructs a 50 minute drama of extraordinary impact, the end of which is an affirmation of their marriage as a spiritual state these partners only half-perceive themselves. I called the film tragic above, but its arc parallels Shakespeare's late romance, THE WINTER'S TALE, right down to a near-miraculous conclusion. A lovely piece of work.
