Secret of the Blue Room (1933)

Shocks! Shivers! Sensation! Surprises! Creeping shadows, clutching hands, a blue death-chamber and a houseful of bewildered men defying the supernatural for the sake of a beautiful girl!...

According to a legend, the mansion's "blue room" is cursed -- everyone who has ever spent the night in that room has met with an untimely end. The three suitors of the heroine wager that each can survive a night in the forbidding blue room.
