Mari is a writer and Jonna is an artist, and they live at opposite ends of a big apartment building, their studios connected by a long attic passageway. They have argued, worked, and laughed together for decades. Yet they’ve never really stopped taking each other by surprise. Fair Play shows us Mari and Jona’s intertwined lives as they watch Fassbinder films and Westerns, critique each other’s work, spend time on a solitary island (recognizable to readers of Jansson’s The Summer Book), travel through the American Southwest, and turn life into nothing less than art.
