When a group of assassins arrive in his city, Drake is told to eliminate them. As he begins to do so, he learns that their goal is to destroy an alternative energy project. Nothing will stand in their way from completing their objective - including innocents.
Drake doesn't want to let uninvolved bystanders die, but his mentors tell him nothing can be done. If he draws attention to himself by warning people, it will put everyone he cares about in danger. Even so, he can't bring himself to stand by and do nothing. He has to walk a fine line and decide what's more important to him: saving countless strangers or protecting the only family he's ever known.
As he kills the assassins one by one, he begins to find out the ugly truth behind his mentors' motives. Not only are they not as pure as he thought they were, but neither is he.
