Helsinki, 1945. The end of the war brings a new sense of artistic and social freedom for painter Tove Jansson. Modern art, dizzying parties and an open relationship with a married politician: Her unconventional life puts her at odds with her sculptor father’s strict ideals. Tove’s desire for liberty is put to the test when she meets theatre director Vivica Bandler. As she struggles with her personal life, her creative endeavours take her in an unexpected direction. While focusing her artistic dreams on her painting, the work that started as a side project, the melancholic, haunting tales she told scared children in bomb shelters, rapidly takes on a life of its own. The exploits of the Moomins, infused with inspiration from her own life, bring Tove international fame and financial freedom. But as she begins to find her artistic identity she has to learn to find herself.
