The Believers Are But Brothers

Writer, director and activist Javaad Alipoor steps into the dark, blurry online world of fantasists and extremists to tell four fictional stories – of an ISIS recruiter, two British recruits and an Alt-right ‘white boy’ from California.

Extremists of all persuasions communicate openly on social media channels and it is here that Alipoor found young men burning with resentment and empowered by digital fantasy. These encounters inspired his acclaimed play which he has adapted for television.
