Two Mothers is a drama about a lesbian married couple, Katja and Isabella, who decided to have a child in Germany, a country that imposes so many legal issues, high fees and other obstacles in a very difficult process. They agreed to find a sperm donor but not a father, so they can educate the child without any exterior interference. Like many lesbian couples in Germany they have to find out that the road to a common child is much harder than expected.
Katja and Isabella are happily married and feel the time is right to have a child. As the weeks and months pass by, it becomes clear that the process will be far more fraught than either were prepared for.
