Vier kriegen ein Kind.

For Neele and her life partner Steff, the dream of having one's own child finally seems to come true: Steff is pregnant. However, there was a confusion in the artificial insemination - instead of their carefully selected sperm donor, they caught a sperm donation from a gay couple: Kalle and Jens also want a baby and consider the confusion as a kind of coincidence. While the two men look forward to their time as active fathers, Neele and Steff see their harmonious trinity at risk.
