When an injury ends his career, Dominika and her mother face a dark and uncertain future. For this reason she is manipulated to become the new recruit of a spy academy, where the agents are called “sparrows”. It is a secret intelligence agency that trains exceptional young people like her to use their bodies and minds as weapons. After a sadistic and perverse training, she becomes the most dangerous “Sparrow” spy that the program has ever produced. Dominika must reconcile the person she once was with the power she now dominates, putting her own life and that of everyone she loves in danger, including a CIA agent who tries to convince her that he is the only person in whom can trust.
