The Insides of Our Lives is a poetic blend of fiction and found footage. A selection of thousands of hours of found footage—mostly 8mm—chronicles the coming-of-age story of two girls growing up along a border in Europe, as the border gradually separates them. The story sensitively depicts what it means to grow up in a world where, one day, barriers appear, creating an “us” and a “them.” The film, though composed of footage from hundreds of different lives that were filmed, is crafted in such a way that it feels like the life of a single person.
