The Crimson Gardenia (1919)

Overview

Wastrel New York millionaire Roland Van Dam travels to New Orleans during Mardi Gras, looking for adventure and romance. Because the costume he is wearing includes a red gardenia, he is mistaken for escaped prisoner Emile Le Duc by a woman (who turns out to be a long-lost cousin) who was to meet Le Duc, who was to be wearing a red gardenia. It turns out that Le Duc is the head of a vicious gang of counterfeiters, and Roland winds up getting in more adventures than he had hoped for.
