A new generation of human-like robots -- "hubots" -- provide all manner of services to the human race. But some of these hubots, known as the "Children of David," free themselves from the control of their masters.

Kidnapped by traffickers and separated from other rebel hubots, the hubot Mimi is sold on the black market. Another Child of David, Leo, leaves the protection of the group and goes in search of her.

Bea and Cloette have finally located David’s clone, but the brain is missing. They continue their search while Tobias and Matilda investigate the code on the USB drive. A segment is missing and Matilda suspects that Mimi knows more than she lets on. When Roger is sent out to pick up a hubot, he’s in for an unpleasant reunion. Florentine’s dream is about to come true - she’s finally going to marry her Douglas. But perhaps human life is not all it’s cracked up to be.

Douglas and Florentine plan their wedding, and Claes can’t help interfering. Back at the Engmans’, Lennart’s clone is increasingly obstinate, in particular towards Hans, who is starting to lose patience. Mimi is hired at the law firm, but not everyone likes having a hubot as a colleague. The conflict between Real Humans and the Transhumans grows increasingly antagonistic. Sooner or later everyone will have to choose sides.
