"Friday Night Dinner" follows the Jewish middle-class Goodman family as they have Shabbat dinner. The family is made up of the mother Jackie Goodman (Tamsin Greig), father Martin (Paul Ritter), elder son and musician Adam (Simon Bird), and younger son and estate agent Jonny (Tom Rosenthal). The show depicts the numerous interruptions to their dinner. These disruptions are often caused by the sons playing pranks on each other or by their neighbour, Jim (Mark Heap).
