In the heart of Germany, a 44-year-old filmmaker named Garrett has become a father to 30 children through private sperm donation. This documentary explores the unconventional lives of the families he has helped create, focusing on the complex dynamics of the donor, the mothers, and the children who are all connected through this unique arrangement. As the children grow, they navigate their identities and relationships with their biological father, while the mothers grapple with the challenges of raising their children in a non-traditional family structure. The film offers an intimate look at the bonds that form between these families, the legal and emotional complexities of their situation, and the enduring question of what it means to be a family in the modern world.
