Beginning with the appearance of two cadavers in a miserable hovel in a poor Havana neighborhood, Lieutenant Alain Bec's investigation takes him once again to an unknown world, something also hidden from view for the majority of Cubans: homosexual and transvestite prostitution directed at foreign tourists, as a form of survival in the face of the economic and social debacle that exists in the country at the time of the plot. Searching for the reason of a supposed suicide in which no one believes, again the two men, Alex Varga and Alain Bec, reveal to the reader a world that is corrupt and rotten, where money, fear and violence dominate everything.
