But things quickly change when a Russian is murdered, execution-style, and three flight crew members die in suspicious circumstances. When Russian intelligence officer Slava Kadun arrives in Havana warning that a CIA hitman has plans to assassinate Raúl Castro, Ramirez starts to wonder if the deaths are connected. With the political future of Cuba at stake, he has only hours to stop a cold-blooded killer.
