Plot

Ireland, 1937. Young Bridie Quilty has grown up listening to her father's heroic tales of the Irish Revolution. As a result, she develops a hatred for everything and everyone British, especially "the wicked murdering blackguard" Oliver Cromwell. By 1944, Mr. Quilty has died. Bridie, who is now 21, sets out for Dublin to carve a life of her own, hoping to join the IRA. On the train, she shares a compartment with J. Miller, a businessman returned from abroad. He is also a German agent who's entered Ireland unencumbered thanks to lax security. He shortly gets his assignment—to break a fellow spy out of prison. Miller recruits Bridie, who gets a job at a hotel and bar in Wynbridge Vale. Soon she becomes acquainted with a certain sergeant, who unwittingly provides her information about the prisoner's impending transfer to London. Meanwhile, Miller is disturbed by the arrival of Lieutenant David Baynes, a British naval officer on leave researching a thesis on Cromwell he suspects of being a counter-intelligence agent. To help enable Miller to free the spy he tells Bridie to distract Baynes on the day of the transfer. The implication is clear, she is to use her wiles. Baynes is happy to take her into the country on her half day but is curious by her blowing hot and cold with him. He has nothing to do with the prisoner transfer.
