Pilar Rivera is a beautiful young woman who emerged from the Cuban Revolution as one of the elite assassins Fidel Castro used to stay in power. Pilar is a shadowy figure who had served as a sniper during the revolution. After the war ended, she is sent to Russia for extensive training in espionage and political assassination. When she first comes to the U.S. at the age of 21, she is well schooled in killing with guns, knives and poisons. She has the authority to kill at will. She is first sent to Washington, D.C., to gather intelligence on the government’s efforts to eliminate Castro. She takes a job at Bobby Baker’s infamous Quorum Club, which Baker established with the blessings of Vice-President Lyndon Johnson for the purpose of spying on political figures in Washington.

Pilar and the other girls who work at the club are in reality call girls who are there to service the sexual needs of club members. JFK is an honorary member of the club, and it’s through this connection that he meets Pilar - for the second time. His first encounter with Pilar had come five years earlier in Havana, when Pilar was a 16-year-old virgin who had been forced into the sex trade by members the Santo Trafficante organization. JFK did not remember that encounter. But Pilar did. She vowed revenge at the time. And now she was about to get it.
