Branded as fugitives by the Federation they swore to protect, the crew dutifully returns to Earth to face charges for crimes committed in the course of rescuing a resurrected Spock, but while en route, they learn that Earth is being ravaged by a strange alien probe demanding a response from a life form that no longer exists.
A massive alien presence of enormous power enters Federation space destroying three powerful Klingon cruisers and neutralizing everything in its path. As it heads towards Earth, Admiral James T. Kirk returns to the helm of an updated U.S.S. Enterprise and sets course to meet the aggressor head-on.
