In July, Tegan and Sara revealed Fanatical: The Catfishing of Tegan and Sara, a Hulu documentary that dives into Tegan Quin’s experience with identity theft and how a catfishing scheme impacted her and their fans, some of whom were targeted by the impersonator.

The first trailer for the documentary has now been released. It begins with Tegan and Sara reflecting on their rise to fame and their early connections with fans through the internet. Soon, viewers hear from fans, some of whom thought they had developed close personal relationships with Tegan.

“I had become friends with Tegan, and it had become a long-term friendship,” one fan recalls. “At some point, she sent me a shared drive and a password. It felt off, so I reached out to her management, and I got a text that says, ‘She has no idea who you are.’ And I said, ‘Well, then Tegan has a big problem.'”

The scammer, who pretended to be Tegan, gained access to her private information and files, leaving the sisters concerned for their safety. Directed by Erin Lee Carr, the documentary premieres on Hulu on October 18.
