Four women, four life plans, and a lot of explosive material. What if Sina can't get pregnant? What if Mona never had children? Would the world be a better place because of it? Yes, believes climate activist Eva Lohaus: Only a stop to births can still save our planet. While she struggles with the consequences of her radical vision, sisters Sina and Mona grapple with their own life choices. From a distance, they envy each other; up close, they pity one another, as they collectively try to resist responsibility and societal pressure. But it is the encounter with Mona's new neighbor that truly changes their perspective on motherhood.

What arguments exist today against having children, and what arguments support it? In her precise and strikingly unadorned language, Verena Kessler tells the story of four women who find their own answers to this question.
