Yellow Canary

In the Second World War, Sally Maitland (Anna Neagle) appears to signal Nazi planes to bomb England after murdering an innocent citizen in his home. The next morning, Sally boards a ship bound for Canada. Two of her fellow passengers, Jim Garrick (Richard Greene) and Polish officer Jan Orlock (Albert Lieven), seek her acquaintance, despite her long-time and well-known admiration for Nazi Germany. It soon becomes common knowledge that Jim is a British intelligence officer. Sally rebuffs his advances, but welcomes Jan's attention. Sally is, in fact, a deep cover British agent on a secret mission shadowing her quarry: Jan. Unbeknownst to Sally, Jim has been assigned to help and protect her.
