The story of Prince Philip's mother Princess Alice, a great-granddaughter of Queen Victoria who married into the Greek royal family, but was forced into exile when revolutionaries overthrew the monarchy. She then suffered a severe nervous breakdown, which led to spells in mental hospitals and experimental treatment from psychiatrists including Sigmund Freud. However, she eventually won her battle with mental illness and became an unlikely hero during the Second World War, before dedicating the rest of her life to working with the poor in Greece.
