You know the expression Sunday Christian? Well, Mahmud Nasir [Omid Djalili] is the Muslim equivalent. He prays five times a day… mostly; he hardly ever swears… he says, and maybe, after a stressful day, a bit of pale ale may pass his lips. In his heart, though, he is a fervent Muslim with a good life – a beautiful wife, Saamiya [Archie Panjabi]; a son, Rashid [Amat Shah] upon whom he dotes, and a successful taxi business. The only real flaw in his life is a curmudgeonly rival cabbie named Lenny [Richard Schiff].
