Edgar G. Ulmer's Club Havana is Grand Hotel, PRC style. The titular club is a popular nightspot where everyone who is anyone congregates. Six couples, none of whom are acquainted with the others, show up at Club Havana on one fateful evening, and the result is sheer murder-literally. Among the participants in the heavily plotted proceedings are suicidal socialite Rosalind (Margaret Lindsay), novice doctor Bill Porter (Tom Neal), callous playboy Johnny Norton (Don Douglas) and would-be philanderer Willy Kingston (Ernest Truex). Former Paramount leading lady Gertrude Michael delivers a poignant cameo as a worn-out powder room attendant.
