Glorious '39 is a tense psychological thriller, from acclaimed director Stephen Poliakoff, about a young woman who uncovers dark secrets about Britain's relationship with Nazi Germany in the lead up to the Second World War.

She discovers some innocent-seeming recordings of meetings - but as she begins to understand quite what her discoveries mean, a tangled web of dark secrets begins to unfurl. People who have come into contact with the recordings are threatened and even die. The innocent certainties on which her life has been based dramatically unravel and amidst a growing sense of menace and betrayal, she has to confront the bitter choice she will be forced to make.
