The Strange Affair plot
"His name is P.C. Strange... Her name is Frederika... All of tonight's secrets will be used against them tomorrow!"
Detective Pierce is informed that a large quantity of drugs will be delivered to Quince, the head of a family of criminals in London. But the bandits are warned by the corrupt Inspector Evans and so they are not caught. Pierce knows Evans is behind that failure and is determined to catch Quince himself. Agent Pete Strange is seduced by the very young "Fred" March, but is oblivious to the girl's ties to the underworld. He is beaten up by Quince's men, but cannot identify anyone because they are masked. Pierce and Strange then decide to work together.
