The Insides of Our Lives is a poetic blend that combines fiction with found footage. A selection from thousands of hours of found footage - mostly 8mm material - tells the coming-of-age story of two girls growing up along a border in Europe, as the border gradually drives them apart. The story sensitively portrays what it means to grow up in a world where one day fences appear, creating an 'us' and a 'them'. The film, though composed with footage of hundreds of different lives that have been filmed, is crafted in such a way that it feels like the life of one person.
