Set in 1958 Havana on the brink of revolution, the series follows Marisol Vega, a legendary bolero singer at the Tropicana Club. While she appears to be the darling of the American mafia and high society, Marisol is actually a high-level asset for a subterranean resistance movement. As the political tension reaches a boiling point, Marisol must use her proximity to a visiting US Senator to steal codes that could change the fate of the Caribbean, all while maintaining her persona as a tragic, love-obsessed diva.
