In Kontiolahti, Mikko is building a willow hut. The purpose is to find out if homemade fishing equipment works better than factory-made ones. In the wilderness of Käsivarre, Aki and Äijä wake up from the shelter of a warm hut. The return trip is already looming ahead, but before that, you should also get fresh fish to take home. Mehtämiko's journey in Finnmark continues in a sweaty atmosphere. Milla and Samuli, on the other hand, start the fly fishing season in frozen waters. Teemu and Mima harness the nearby bird tower for use and promote the Helmi habitat program in the field of small game hunting.
