Netflix's new documentary Our Father follows the story of a twisted fertility doctor who secretly impregnated his patients as part of a 'sick experiment'.
The show tells the story of disgraced GP Donald Cline - who committed the real life crimes to women as they visited his clinic, secretly fathering 50 children after telling his patients the sperm used was from volunteer donors - when it was actually his own.
His first victim realised the shocking truth in 2016 - when she discovered Cline was her biological father.
