Molina isn’t the only one hunting Semyonov. He faces a deadly obstacle in the form of a mysterious mercenary known only as Medusa .

Medusa is a ghost—a cold-blooded assassin whom no one has ever seen and who reportedly knows no fear because she has long since lost all hope. Her only goal is to look her victim in the eye and deliver their death, much like the mythological figure of her namesake. Why It Appeals to Fans

The world is depicted as cynical and dangerous, where "good" and "bad" are often just different shades of survival.

Molina is tasked with capturing Mechislav Semyonov , a ruthless Russian criminal kingpin operating out of Italy. Semyonov’s empire is built on the darkest corners of the black market: international arms and drug trafficking, human organ sales, and prostitution.
