1950's, Leeds: Betty (Billie Piper) is a wife and mother, whose life  is changed forever after falling hopelessly and dangerously in love with her charismatic Polish neighbour, Alex Crazenovski, better known as "Craze". Against her principles, she soon abandons herself to a world of untapped thrills and passion, a world that has been so desperately missing from her own conventional and claustrophobic marriage. But 30 years later, an older Betty (Sue Johnston) comes to realise that her compulsive passion of the past and its consequences have created ripples that spill far into the future, finally reaching crisis point on her beloved son’s wedding day.
