Wesley Gibson is a bore and a whiner who stays in the office all day long. His boss humiliates him, his girlfriend cheats on him. His life is going nowhere! After discovering that his father, who abandoned him in early childhood, was brutally murdered, Wes finds himself drawn into a secret society of killers called "The Brotherhood". He is trained by Fox, an experienced mentor, and this once chained to an office chair develops lightning-fast reactions and superhuman speed. However, already on the first task Wesley realizes: there are things more difficult than to decide the fate of other people. It is to gather courage and become the master of his own life.
