1981
In the middle of the Cold War, Russell Adler discovers during a mission that Perseus, his sworn enemy is back after more than 13 years of silence!
From this discovery, President Reagan gives him full access in the hunt for Perseus: he therefore forms a team of the best agents that the West can offer!
In his team is Helen Park, MI6 field agent and one of Adler's best assets against Perseus. Adler also hired "Bell", an MI6 agent who participated with Adler in Operation Fracture Jaw in 1968 in Vietnam!
"Bell" and Park knew each other by sight but despite Adler's advice asking to keep relationships only professional, that will not prevent them from getting closer in their hunt for Perseus!
