Desi Arnaz played the owner of a gambling club in Havanna. Amazingly Arnaz made a superb romantic action lead. With his hair cut short and a clipped vocal delivery, Arnaz was in the same acting league as Bogart in Casablanca. Arnaz was even credible in a fight scene where he apparently used martial arts. The photography of the episode had a beautiful film noir sheen.
The rest of the cast was almost as good as Arnaz, which is saying a lot. Rod Taylor was excellent as an American agent, but he was killed off early to let Arnaz do the heroics. Akim Tamiroff and George McCready also gave good value in support.
Arnaz was an amazing talent. Sit-com star, singer, producer, and romantic lead. This could have been a fine series for Arnaz. I wonder if it was intended as a pilot.
