Beatriz is a 22-year-old exile from Cuba living in Palm Beach, Florida, with her wealthy family. Restless and deeply affected by the loss of her former life, she rejects the domestic future her parents envision for her.

Eduardo is a pragmatic and attractive Cuban exile who was best friends with Beatriz's late brother. He shares Beatriz's desire to reclaim their homeland and often reminisces with her about dancing at the Tropicana. Operating in secret circles with his own agenda, he connects Beatriz to the CIA while simultaneously worrying about the danger she invites into her life.

Dwyer is a taciturn and observant CIA agent orchestrating operations against Fidel Castro's government. Recognizing Beatriz's thirst for revenge and her ability to blend seamlessly into high society, he views her as an ideal asset for intelligence gathering and high-stakes assassination plots.

Alejandro is Beatriz's twin brother who participated in student protests at the University of Havana against Batista's rule. His violent murder at the hands of the new regime continues to haunt Beatriz, serving as the core motivation for her espionage.
