In Britain, four men are determined to enforce their beliefs. Omar (Riz Ahmed), unhappy about the treatment of Muslims throughout the world, has a plan to help right that wrong. Omar's friend Waj (Kayvan Novak), loves the idea and loves even more that Omar is willing to think for him all the time. At the other end of the spectrum, a recent Islamic convert (who is, consequently, white) named Barry (Nigel Lindsay) is opposed to basically everyone and everything he encounters, trying to be his own person. Faisal (Adeel Akhtar) is the last member of the odd group, and he is a bomb-maker who suddenly changes his ideals when his father becomes ill. It is up to Omar to find a way to rally this unlikely group of men and do something noteworthy for their cause.
