A massive alien spacecraft of enormous power destroys three Klingon cruisers as it makes its way toward Federation space. The only starship in range is the USS Enterprise. After undergoing a major overhaul in drydock orbiting Earth, Admiral James T. Kirk is ordered to take command of his old ship for the first time since her historic five-year mission. Kirk rounds up the rest of his crew, acquires some new members, and sets off to intercept the alien spacecraft. However, it has been three years since Kirk last went into deep space - is he up to the task of saving Earth?
