Hanna is now secretly trying to destroy Utrax from the inside and free herself from its grasp with the help of her previous nemesis, former-CIA agent Marissa Wiegler. Together they have coerced high-ranking Utrax agent John Carmichael into aiding their mission, but her fellow young assassins, Sandy and Jules, and new foes are starting to suspect Hanna's plot. As Hanna moves closer to her goal, she begins to uncover not only a world-changing agenda but the true power behind Utrax that stands between her and freedom.

In Season Two, Hanna risks her freedom to rescue her friend Clara from the clutches of the Utrax program, now run by John Carmichael and his second in command, Leo Garner. Hanna finds help in the unlikely form of her previous nemesis, CIA agent Marissa Wiegler, who must protect both herself and Hanna from the ruthless organization she once trusted. Yet as Hanna delves deeper into the elusive world of The Meadows and meets others like herself, including Sandy and Jules, she begins to question her role in the larger context of Utrax's assassin program and ultimately, where she truly belongs.
