The Black Raven (George Zucco) - not his real name but the name he is known by due to his criminal activities - owns a hotel on the Canadian border. A number of people wanting to cross the border for various illegal reasons get trapped by a storm and a broken bridge and end up in the hotel. The people include an escaped convict (I Stanford Jolly), a man who robbed a bank (Horace Weatherby), a crime boss on the run and an eloped couple. The latter are rumbled when the girl's father, an important man, turns up.
When the father (Robert Middlemass) is found murdered, suspicion falls on the future son-in-law (Robert Livingstone) though the Black Raven turns out to be a criminal with a heart of gold and wants to prove the young man's innocence. When the stolen bank loot goes missing and the crime boss (Noel Madison) also ends up dead then the Sheriff (Charles Middleton) has a real mystery on his hands...
A fun if sometimes confusing film. The setting up takes ages with probably a few too many characters and the action takes place largely in the dark with various bumps and scrapes. Despite the heavy number of characters they all have time to establish themselves and the elaborate story makes sense in the end. It is what you would call a romp.
