A homage to Krišjānis Barons and his life's work – to collect and catalogue Latvian folksongs or dainas,thus creating the encyclopaedia of Latvian life, a poetic reflection of the knowledge of life accumulated over the centuries. The film is based on Krišjānis Barons' life during late 1800s and early 1900s – his childhood and youth in Latvia, studies and work in St. Petersburg and other places in Russia, his relationship with his faithful wife Dārta, and the awakening of the Latvian self-awareness.

A young couple of biologists and their two children move from Riga to a nature reserve where they're provided with an old country cottage. They start to repair the cottage and feel at home, but the former owner of the house suddenly returns from Canada. When he realises that the present inhabitants have kept the spirit of the place alive, he gives up his rights to the cottage. The film then concentrates on him coming to terms with his memories of his time as a guerilla, when he found his first love, his 'sister-in-arms', who betrayed him fifty years ago. The film also investigates the relationship between the young biologists and nature, and the process of reaching adulthood. The title of the film, The Nest, stands for the surroundings of living nature (the forest, the marshes, the coast) and more generally for the small fatherland that has to maintain its position among great powers such as Russia, Germany and America: countries that largely shape the fate of the characters.
