There’s a beautiful island in the Baltic Sea, where a group of sailors built their own kingdom. They had it all: seventeen acres of land, endless freedom and a donkey called Geronimo - until their community fell apart. Awoken from an utopian dream, the sailors return to the mainland and to the very society they wanted to escape from. Now they live on rusty ships in an anonymous German harbor town, out of work and out of luck. Each of them is haunted by the island’s dark and compelling promise. Can they ever break through the spell it cast on them? A film with floating contours, a story of stranded sailors and malediction, fed by the imaginary world of the desert island and community-based utopias: «A Donkey Called Geronimo» is a documentary poem that creates a shattered image of utopia, while exploring the boundary between myth and reality.
