With three suitors vying for her hand, heiress Irene von Helldorf (Gloria Stuart) playfully suggests a contest to determine who's worthy-with each having to spend a night in her ancestral castle's "blue room," where a trio of murders were committed a generation before. As the entrants begin to vanish, however, it becomes apparent it's no game. Tidy thriller co-stars Edward Arnold, Paul Lukas, Lionel Atwill, Onslow Stevens. 66 min.
