In an attempt to leave a troubled past behind, Christopher Schmidt (Arnold Schwarzenegger) flees Germany at a young age and moves to the United States, where he changes his last name to "Smith" and serves in the American army. Now retired, Christopher is sought by a secret CIA cell that intends to recruit him to work undercover, carrying out highly dangerous secret services. Chris has no way to refuse the offer, since the organization's directors know the real reason he fled Germany.
