The film is a combination of animation and live-action sequences. In both parts, the connecting thread is the knock on the door. It is a story about a man who finds himself in various situations during his life, even being shot, and after each of those situations, he hears a knock on the door and when he opens it, there is a man in front of it who hits him on the head. That is the animated part, which has 32 frames. The live-action part is made up of 18 frames, divided into two sequences. In the first sequence, the animator makes the cartoon he has already seen, hears a knock on the door and when he opens it, he is also hit on the head by a man. In the second sequence, a woman makes a collection of photographs showing the animator in various situations, and suddenly hears a knock on the door. The dilemma arises whether to open the door?
