In a remote corner of Estonia, in Võru, lives Kalju, who is building a 19-metre-high observation tower with his own hands. He has been doing this for years, all year round. Why does he do this hard work alone? Who is he building it for? Step by step, we discover the story of Kalju, who lives in this fast-paced, chaotic world at his own pace and by his own rules. He believes in his own convictions and keeps on working.
