BAFTA and Emmy award-winning filmmaker Charlie Russell meets the couples who are part of an extraordinary and highly popular new online phenomenon: real couples in real relationships choosing to broadcast their sex lives on the internet. Live and fully interactive, this booming new amateur industry takes the social media concept of sharing everything online to the extreme: thousands of real couples from all over the world are now offering up their sex lives - and the intimacies of their relationships - for a huge audience of online voyeurs.
