Glorious 39

A woman makes a surprising discovery with dangerous consequences in this period suspense thriller, set in 1939. Anne Keyes (Romola Garai) is an attractive young woman who is enjoying modest success as a film actress; she's also the adopted daughter of Alexander Keyes (Bill Nighy), a career politician and Member of Parliament. Anne still lives in the family home with her father, mother Maud (Jenny Agutter), budding diplomat brother Ralph (Eddie Redmayne) and socialite sister Celia (Juno Temple). One night, Hector (David Tennant), one of Alexander's friends, stops by for dinner and during a heated conversation makes no secret of his disapproval of prime minister Neville Chamberlain and his efforts to appease Adolph Hitler's Nazi regime. Another dinner guest, Balcombe (Jeremy Northam) doesn't care for what Hector has to say, and later that evening, Hector is found dead, an apparent suicide. Anne, however, begins to suspect foul play when she finds a set of phonograph records that document conversations of men discussing state intelligence secrets. When Anne ties to share this discovery with others, they're soon found dead, and she's no longer certain what she should do with these deadly secrets.
