Plot synopsis: Even in 1970, films were made, prepared in previous years and expressing the poetics of that time. Ivan Renč created an almost protocol parable, deliberately set outside time and space, playing out a supremely model situation. In a somewhat rambling and not always convincing story, it tells the story of a young prison guard who dreams of living on a lonely lighthouse. He is ridiculous in his own way, with a distorted character, he hardly finds any satisfaction in his job, he cannot command the slightest respect from the prisoners - and the hero then takes out his excess pressure by abusing a defenseless dog. And one day there will be a short circuit meeting.
