Curmudgeonly widower Nat Dayan clings to his way of life as a Kosher bakery shop owner in London's East End. Understaffed, Nat reluctantly enlists the help of teenager Ayyash, who has a secret side gig selling marijuana to help his immigrant mother make ends meet. When Ayyash accidentally drops his stash into the mixing dough, the challah starts flying off the shelves and an unlikely friendship forms between the old Jewish baker and his young Muslim apprentice.

Dough is a warm-hearted and humorous story about overcoming prejudice and finding redemption in unexpected places.
