The Pendon Amateur Light Operatic Society's production of The Beggar's Opera is going off the rails, that is until a handsome but shy young widower Guy (Harman) joins the group. An instant hit with the company's ferociously zealous director Dafydd (Brydon) and the show’s leading ladies, including Dafydd’s wife Hannah (Jensen), Guy soon gets more than he bargained for as he discovers that all the best action happens off-stage. Classic songs fill the air as the drama on stage is mirrored by the romantic rivalry and small-town squabbles causing a stir in the wings of this ambitious local show.
