When a top-secret intelligence agency called The Orphanage becomes convinced it has a mole, analyst Alexander Hale realizes he's the prime suspect; clearing his own name leads to a shocking discovery about his past and the country's future.

Forced into an uneasy alliance, Alexander and The Orphanage must work together to protect their discovery of the hack; relying on a plan from an untested agent named Parker, Alexander and Michelle are dangled as bait in a deadly trap.

Now that his fake life is up and running, Alexander must act like everything is normal – until he realizes that The Orphanage's plan is to use him to personally sacrifice a real mission as a way to learn more about their enemy.

Now in the field, Alexander makes contact with a Source to draw the enemy out; when ambushed, he protects the Source and risks his own life, only to discover that nothing is as it seems; Michelle gets a visit from the past.

When the mission to capture their enemy in Paris goes sideways, Alexander surprises The Orphanage by going off-book and following his own mission plan; this time, it could cost him everything.

Face-to-face with the enemy, Alexander realizes he won't get the answers he needs; instead, he's walked into a trap and given an impossible choice; The Orphanage must decide if Alexander has turned on them.

After appearing to betray The Orphanage, Alexander is on the run from the people who know him best; with Parker hunting him and his body betraying him, he must stay alive long enough to save those whom he holds most dear.

As Alexander rushes toward a final collision with The Orphanage, Parker discovers a secret message that's been hiding in plain sight – leading to a mission within the mission that might be their only chance to save everyone and end the hack forever.
