Information for Marys Seacole at Donmar Warehouse, West End (Play). Mary Seacole was the pioneering Jamaican nurse who bravely voyaged to heal soldiers in the Crimean War. She was a traveller, a hotelier and a businesswoman. She was the most impressive woman you've ever met. Putting the concept of a biopic through a kaleidoscope, Marys Seacole is a dazzling exploration, across oceans and eras, of what it means to be a woman who is paid to care, and how, ultimately, no one is in charge of their own story.
