Gardener Arnold Treumuth's life in the summertime expresses the ups and downs of amateur gardeners during the 1970s in Estonia. The documentary is a continuation to Vello Aruoja's documentary "Gardener's Spring".

A gardener won't rest even when the snow covers the ground and there are frozen flowers on the window glass. Now it is time to take part in the meetings and lectures held by the gardening cooperative as well as purchase new tools for the upcoming season. And of course one has to keep checking the gardening patch. Winter is an important time for a gardener to prepare for spring. The film serves as a continuation to TV films "Gardener's Spring", "Gardener's Summer" and "Gardener's Autumn".

Spring has turned into autumn, and the beauty and yield of the garden have changed.
