Set in Whitechapel in 1888. Fiona Finnegan is the spirited, ambitious daughter of an Irish dock worker. She longs to break free from the squalid lanes and alleys of Whitechapel, where she has a job in a tea factory. With the love of her life, Joe Bristow, she dreams of escaping the poverty and opening her own tea shop. But one by one her dreams fall apart as her father is killed in a dock accident, Joe is seduced by another woman, and her mother is viciously murdered. Devastated, her life in tatters, Fiona flees to New York where she sets up home with her alcoholic uncle. Slowly she builds his small grocery shop into a thriving tea house, and her new life flourishes. After years of hard work, she establishes herself as the head of her own powerful tea empire. But she cannot forget London. Convinced that her father was murdered by his brutal employer, Fiona vows to seek revenge and ruin him once and for all. Making her way back to the streets of her impoverished childhood, Fiona must start her fight again.
