Capt. Jean-Luc Picard (Patrick Stewart) diverts the starship Enterprise from its scheduled trip to Cmdr. Riker (Jonathan Frakes) and Counselor Troi's (Marina Sirtis) wedding to negotiate a peace treaty with the Romulans. Picard is shocked when Shinzon (Tom Hardy), the new Praetor of the Romulans, admits to being a clone of him. When the crew members discover a break-in on their computer, they are forced into a life-or-death battle to stop Shinzon's Warbird before it can destroy the Earth.
