Informer is a sophisticated, character-driven thriller about Raza, a young, second generation Pakistani man from East London (Nabhaan Rizwan) who is coerced by Gabe, a Counter-Terrorism officer (Paddy Considine) to go undercover and inform for him. Gabe, who has a past he is unwilling to expose, is joined by Holly, his new and ambitious partner (Bel Powley) whose endless curiosity becomes threatening to him. As the central counterterrorism investigation heats up, the stakes for all three get higher and higher. Informer tells a story about identity in a world where lines are increasingly being drawn and sides are being taken. What happens when you, or your friends, family or neighbours fall on the wrong side of that line and the personal becomes political?
