Mankind has been obsessed with building humanoid robots for centuries. As the prospect of living with androids draws ever closer, the focus for some is turning to having sex with them. This documentary, filmed over two years, reveals how some companies are trying to combine artificial intelligence and intimacy in a mass-produced automaton. It follows one company as they build a prototype sexbot, called Harmony, and also introduces James, who already owns four sex dolls and cannot wait to have his own cutting-edge artificial girlfriend.
