The Crown Prince (Robert Montgomery) is to marry the Princess Brenda of Irania, but the Princess declines the arranged marriage. Relieved, Florizel heads for London, with the Colonel (Frank Morgan), where he seeks adventure and a good time. Talking with a stranger, he learns that there is a private club called the Suicide Club. Taking this to be a ruse or a trick, he joins in and sees a mysterious Lady that he has met once before on his way to London. He will find that this club may not be a ruse and that the cold dark stare of this Lady might cost him dearly.
