Merthyr Tydfil 1867 There's a new emerging star of the stage, called, 'Kathleen O'Hara'. Unfortunately for Irish-born, Kathleen, although she's described as having the 'Voice of an Angel', as she successfully performs on the stage at The Temperance Hall, Merthyr Tydfil, it's not plain sailing. She has the wrath and jealousy of operatic diva, Bella Montovani, to contend with. Up until now, Bella, has had top-billing at the theatre, but she views Kathleen as competition. The young Irish woman is better looking and her voice draws an appreciative audience, whilst Bella's popularity wanes. Newly-married Kathleen, also has opposition from her own husband to contend with. He's just landed a job with the Glamorgan Constabulary, whilst she has the chance to head for the London stage, causing conflict between the pair. Will Kathleen pursue her dream and head for London without her husband or stay put on the Merthyr stage?
