Synopsis:A young boy known as Durant is accosted by a drug dealer and some addicts. He kills them in defense and a gun shot is heard. Flash forward to the present, the boy is now in his 20s and attending college. He lives a reclusive life and puts on a fake, gregarious disposition when he's forced to socialize.
Meanwhile, a group of men (Alpha team) under the orders of the chief of a state police are hunting down Xaphan, a boy who bears a striking resemblance to Durant. A flashback follows up on the opening scene. The gun shot was fired by a man named Vergil to end a fleeing druggie's life. Vergil compliments Durant's commitment to justice and to battle immorality. Vergil offers Durant a chance to join him to rid the world of corruption.
Back in the present, Alpha team spots Durant at a restaurant with his suitemate. They trail and spy on him at his university. At night, they follow him to a deserted hardware store supply yard. Alpha team arm themselves and set out to kill Durant, only to meet their deaths from an ambush by Durant.
The chief is reprimanded by Henry Wagner, the director of the department known as HIDE. Durant used to be part of a program known as Harbinger for Blackshield. As a clandestine department of private military contractor Blackshield, HIDE's (Harbinger Investigation Department of Eradication) goal is to subjugate Durant.
Durant goes to his parents' home for the holiday break. Despite their care for him, he is distant with his family and focuses more on researching his situation. Durant experiences another flashback of his Harbinger days where he recall his first assassination mission.
In the present, Durant drives to Chicago to meet an ex-Harbinger operative who now devotes his life to peace, Curtis Freeman. Their meeting is interrupted by Curtis's family. Durant has lunch with them and privately talks to Curtis afterwards. Durant reveals to him that he and Vergil bombed the Harbinger base several years ago. Curtis isn't able to provide any useful information, which prompts Durant to seek out Helena, an ex-Harbinger staff who is actually working for Wagner's team.
Curtis drops Durant off at his parking garage where Durant is attacked by a HIDE operative. Durant kills him and escapes from the local authorities in a thrilling foot chase. He seeks refuge in a grocery store, only to run into an old friend, Beatrice. He hitches a ride with her to escape from the city.
At Beatrice's apartment in Peoria, Durant and Beatrice briefly catch up with each other. Not wanting to endanger Beatrice's life or let her know what he has done, he leaves for a hotel. There he is pursued by two assassins. One of them is Jaeger, who saves him from a group of armed men for mysterious reasons and tells him to head to the Franklin Street bridge.
A riveting car chase ensues with the other assassin chasing him along with the local law enforcements. Durant does as Jaeger suggested and uses a railroad to cross to the other side of the bridge. Bombs detonate on the tracks. Durant leaps into the water for safety, while his assassin pursuer is killed. Durant crosses over to dry land before collapsing from exhaustion. He is rescued by Vergil who informs him of how he faked his death and his ploy with Jaeger to rescue him. Vergil also tells Durant that he learned from Jaeger that HIDE's base of operation is in Sacramento. On the way to the airport, Vergil divulge his plan for the two of them to meet up at the Folsom Dam and bomb it, flooding the city to destroy the HIDE base and to rid the city of its decadence. Vergil plan for them to split up at the airport to avoid suspicion.
While waiting for the operation to start at a hotel in Sacramento, Durant looks outside his window at all the possible people that will be killed if the plan is a success. During his watch, he spots Jaeger for a second before Jaeger disappears. Durant confronts Vergil at the Folsom Dam and affirms he won't be helping him. The two are interrupted by a team of Blackshield soldiers. Vergil and Durant take them out together before turning on each other. A fierce sword duel is fought between former master and apprentice, while the dam begins to blow up. Durant emerges the victor, but discovers that the bombs cannot be switched off.
He escapes the dam in time, only to helplessly watch the water rush towards the city. Thus, ends the first part of a trilogy.
