In West Berlin in 1989, eighteen-year-old Ralf has just left school and is living a final golden summer with his three best friends. They spend their days swimming, smoking and daydreaming about the future, oblivious to the storm gathering on the other side of the Berlin Wall.

But an unsettling discovery about his family and a meeting with the mysterious Oz shatters everything Ralf thought he knew about love and loyalty.
