A determined 12-year-old boy named Ivan joins a Russian partisan regiment as a scout due to his uncanny ability to slip quickly through enemy lines undetected. But as his missions become increasingly dangerous he is pulled from duty, something which he is quick to protest against because Ivan has an ulterior motive - to avenge the death of his family at the hands of the Nazis. Andrei Tarkovsky’s first feature film is regarded as one of the most accomplished debuts in cinema and launched the career of the most influential and admired Russian filmmaker in history.
