The unexpected difficulty of becoming mothers through the means of artificial insemination slowly erodes the relationship between Katja and Isabella.

Katja and Isabella decide to have a child. However, like many lesbian couples they discover getting pregnant is difficult since (for legal reasons) most fertility clinics refuse to treat them. Help is available at one clinic but for a price. After several expensive attempts Katja wants to stop while Isabella refuses to give up. In a last effort, the couple purchase an “at home” insemination kit and search a “sperm donor” website. And so they begin ‘casting’ for a potential donor – a process that challenges both women’s attempts at creating a family.
