Oscar-nominated actress Julie Walters takes on the lead role in a revealing portrait of Mo Mowlam; the woman whose charisma and no-nonsense approach to politics helped achieve one of the most monumental landmarks in recent British history, the Good Friday Agreement. Arguably the most popular, if controversial, Labour politician of a generation, Mo's warmth, passion and unorthodox style made her renowned throughout the country and loved by many. Away from the public gaze, she found happiness in later life with husband Jon Norton (David Haig - My Boy Jack ), but just months before the pivotal 1997 general election, she discovered she had a brain tumour. Defying medics, her brave battle with ill-health was played out on the public stage.
