Hanna (Esme Creed-Miles) has grown up in a forest with her father Erik Heller (Joel Kinnaman), without contact with other humans. No one can know about them. But when they are discovered, both try to escape from a CIA team led by Marissa Wiegler (Mireille Enos) that wants to capture them.

In season two, Hanna risks her freedom to rescue her friend Clara (Yasmin Monet Prince) from the clutches of the Utrax program, now run by John Carmichael (Dermot Mulroney) and his second-in-command, Leo Garner (Anthony Welsh). On one of her trips, Hanna arrives to the city of Barcelona to stop one of Utrax's plans.
