Jan Mycrobatt wakes up disoriented in a mysterious laboratory of the underground terrorist group Riot. He has no recollection of who he is and could only remember the existence of his wife and child. He finds out that Riot has been using him as a human test subject for their new technological breakthrough: EAGLE, a merciless killing machine in the facade of a human. Their goal was clear: to use him on People's Day, an annual peace event attended by numerous ambassadors and leaders. This year, it is to be held in their city, Crest, and they plan to use Jan to assassinate the high-ranking attendees. Throughout all of this, one question keeps repeating itself in his mind: Why him?
