Dutch docu-series “Seeds of Deceit” tells the disturbing story of Dr. Jan Karbaat, a pioneer in the field of artificial insemination who secretly used his own sperm to impregnate his patients.

Across three episodes, director Miriam Guttmann weaves a complex narrative which balances the perspectives of the women abused by Karbaat, the dozens of children he fathered, and the “superdonors” who returned to his clinic over and over again to illegally “spread their seed” far and wide.

“Seeds of Deceit” was the first Dutch series ever to debut at Sundance and is now positioned for a global sales foray as one of the Series Market Selects at Berlinale.

Variety caught up with Guttmann and Monique Busman, who co-produced alongside Michiel van Erp, to discuss the show’s jaw-dropping revelations and their thoughts on how to ensure that Karbaat and his friends’ twisted actions will never be repeated.
