In 2005, Spain legalised same-sex marriage and adoption by same-sex couples. Many minors born before the law was passed, who had same-sex parents, found themselves in a legal limbo, forcing them to bear only one parent’s surname.

This film tells the story of Roger, a teenager with two mothers, Cristina and Esther, highlighting the complexities of assisted reproductive techniques and how scientific advancements often outpace the law. Roger, who only carries the surname of Cristina (the mother who gave birth to him), initiates a legal process to have Esther recognised as his legal mother. This process underscores the bureaucratic challenges and social prejudices that persist to this day.

The film also examines the definition of family, as well as the emotional and legal complexities of having two mothers. Blending archival materials and personal narratives, the film shows us how this problem affects other families and the shortcomings of contemporary cinema in presenting family diversity in our society.
