In a British city, four men have a secret plan. Omar (Riz Ahmed) is disillusioned about the treatment of muslims around the world and is determined to become a soldier. This is the most exciting idea Waj (Kayvan Novak) has ever heard. Better still it's a no brainer because Omar does his thinking for him. Opposed to Omar and everyone else on earth is the white islamic convert Barry (Nigel Lindsay). He'd realize he joined the cell to channel his nihilism - If he had half the self knowledge of a duck. Faisal (Adeel Akhtar) is the odd man out. He can make a bomb - but he can't blow himself up just now coz his sick dad has 'started eating newspaper'. Instead he's training crows to fly bombs through windows. This is what Omar has to deal with. They must strike a decisive blow on their own turf but can any of them strike a match without punching himself in the face?
