Maggie Stuart appeared as grasping vixen Iris Pendleton, (the villain of the piece) who co-owned the Pendletons Health Studio with her nerdy brother-in-law Norman (Garth Meade), whom she is conniving to get rid of, with the aid of the dim-witted gym instructor Len Crosby (Bill Charlton), with whom she became pregnant. Iris had been married to Norman's late brother, Michael. Coral Drouyn, billed as Coral Kelly, played Consuela McPhee, the newly hired 'full figured' receptionist at the Health Studio, who was despised by the vengeful Iris. Despite this, Consuela and Norman became a mismatched set of friends.
