In France, 2.5 billion of used diapers must be disposed ever year. An example of the cost to the environment and to families for having a child. Is the change from disposable back to reusable cloth diapers a return to the past or a wise choice in sustainable habits? What are other countries doing about this problem? Drawing on interviews with researchers, industrialists, consumers and feminists, the film seeks to answer questions about an emancipatory product of today's consumer culture.
