A devoted Muslim family man experiences a hilarious identity crisis after discovering that he was adopted at birth, and his real name is Solly Shimshillewitz. Mahmud Nasir (Omid Djalili) is still grieving the recent death of his mother when he finds his birth certificate, and learns he was born to a Jewish mother. In order to embrace his heritage, Mahmud seeks the advice of drunken cab-driver Lenny (Richard Schiff), whose crash course in Judaism is more quirky than kosher.
