During Operation Desert Storm, CIA operatives Troy Marshall and William ""Case"" Calderon are deployed to the Iraq-Kuwait border to extract an Iraqi official. The mission goes sideways when the target claims he is being hunted by a shadowy paramilitary force called Pantheon. After the extraction fails, a rogue former agent named Russell Adler surfaces with a cryptic message pointing to an old KGB safe house in Bulgaria. Suspended from duty and with no official support, Marshall, Case, and veteran operative Frank Woods assemble a team of outcasts, including an ex-Stasi technician and a skilled assassin. As they dig into Pantheon's operations, they uncover links between the group and CIA leadership itself, along with a dangerous psychochemical weapon called the Cradle. Declared fugitives after being framed for a Pantheon attack, the team must unravel a conspiracy that reaches into the highest levels of American intelligence.
