Build a movie plot around this: Who cornered Waj? The police
A group of radicalised young British Muslim men aspire to be suicide bombers. They are Omar (Riz Ahmed), who is deeply critical of Western society and imperialism; his dim-witted friend, Waj (Kayvan Novak); Barry (Nigel Lindsay), a bad-tempered and extremely rash white convert to Islam; and the naive Faisal (Adeel Akhtar), who tries to train crows to be used as bombers.

The visit to the training camp ends in disaster, with Omar misfiring a rocket backwards that kills fellow jihadists; however, he uses the experience to assert authority on his return to Britain.The group begins acquiring materials for making improvised explosive devices but disagree about what to target.

Faisal accidentally trips in a field while carrying the explosives and blows up. This causes a row among the remaining four, who disband; but they reconcile, and Omar decides to target the upcoming London Marathon.Wearing mascot costumes to conceal their explosives, they prepare to attack. Waj expresses doubts about the rectitude of the plot, but Omar convinces him to go ahead.

This causes the police to search for the remaining three.Omar realises he has led an unwitting Waj into something he does not want to do and tries to change his mind. Police attempt to shoot Omar as he mingles with other runners but, instead, shoot a bystander dressed as a Wookiee. Omar...
