It’s the height of lockdown, 19-year-old Ellie Williams claims on social media she's been raped and exploited by an Asian grooming gang across the north of England. Photos of her alleged injuries add to the outrage and the post goes viral - shared more than 100,000 times.  

Social media rumours lead to attacks on Asian men and businesses in her hometown of Barrow-in-Furness. But when she's arrested for perverting the course of justice, things really explode and there are protest rallies and claims of a cover-up.  

At her trial, the prosecution say she lied, faked text messages and even caused the catalogue of injuries to herself.    

In season 6 of StoryCast, Sky News' Jason Farrell and Liz Lane, who reported on the case at the time, return to Barrow to investigate what could have led her to make these claims and if, underneath it all, there is some other truth buried among the lies.  

With access to her family, police investigators and those most impacted by her allegations, we ask: Is Ellie Williams a villain - or a victim of something else? And what happened after the trial - once all the media attention died down and new allegations began to emerge?
