It is late in 1946. The American Mafia is finding Cuba an excellent place to make a lot of money away from the prying eyes of the US Feds. The CIA is concerned that the mobsters are becoming very close to the Soviets and they sent two of their agents, Erika Lehmann and Zhanna Rogova, to Havana to infiltrate the mob and learn what they can. They do this by becoming bodyguards to Bugsy Siegel.
