Seth lives with his friend Freek, a German who is always dressed in a leather suit, while his twin sister Fiona lives with her son Roel. We follow the struggles between the twins and the turbulent emotional lives of the two. For example, Seth feels that he was born in the wrong body, which leads to a lot of jealousy towards Fiona. After her husband's divorce, Fiona plunges into the wild single life, which in turn leads to disapproval from her son, who finds a different man in their bathroom every morning.
