Serial killer known as "the avenger" is murdering blonde women in London.
A new lodger, Jonathan Drew, arrives at Mr. and Mrs. Bounting's in
Bloomsbury and rents a room. The man has a strange behavior, he goes out
during foggy nights and keeps a picture of a blonde girl in his bedroom.
The Bounting's daughter, Daisy, is a blonde model and she is engaged to
Joe, a detective. When Joe finds out that Bounting suspects Jonathan,
he is jealous of the lodger flirting with Daisy and arrests the man accusing him
of being the avenger.
While the policeman is driving the prisoner to Scotland Yard, Jonathan runs
away, but he is soon trapped on a gate. An angry crowd is going to attack
him, when Scotland Yard tells Joe that the real avenger has been captured; thus,
the lodger is safe.
The blonde girl in Jonathan's picture was the man's sister, one of the killer's
victims. The lodger was going out during foggy nights to find the killer on
his own.

This is the director's first thriller movie. We find the theme of the suspected
innocent man who has to investigate on his own to find out the real guilty.
This is a recurring device in Hitchcock's cinema.
