We see a sound engineer (Jitka Borkovcová) playing back a recording on a reel-to-reel tape recorder. A tongue twister is recorded on the tape. The voice of an man (Tomáš Černý) keeps repeating the tongue twister. After a larger number of repetitions, the voice occassionally fluffs a word, or stutters. At that moment the sound engineer stops the recording and locates the place with the stumble by turning the spools. She cuts it out, sticks the tape together and carries on. We see the flawless edit being reeled onto the right reel, but we never get a chance to listen to it again. Thus we only see the resultant flawless version of the tongue twister, but never get to hear it.
