Once a secret government assassin, Evan Smoak walked away to help others.
But when his old handler calls with a warning - the Orphans are being killed off - he also receives a final mission.
A young girl - the last Orphan recruit - is in danger. First, Evan must find her. Then he must protect her.
But those tasked with her elimination will not stop.
And leading them is one of Evan's fellow Orphans - who'll do anything to see him dead...
