Star Trek Nemesis

On Romulus, the Senate rejects an approach from the Reman leader Shinzon and is promptly wiped out by a deadly weapon. On Earth, meanwhile, the Enterprise crew celebrate the wedding of Riker and Troi, with Data singing “Blue Skies” at the reception. Heading for Betazed and a second ceremony, the ship detects a positronic signal on Kolarus III, near the Romulan Neutral Zone, and the crew recover the scattered parts of B-4, a simpler android almost identical to Data. Admiral Janeway then sends the Enterprise to Romulus, where Shinzon, now praetor, says he wants peace with the Federation.

Shinzon proves to be a clone of Picard, created by the Romulans as part of a plan to replace him, then abandoned on Remus when the scheme was dropped. He has built an enormous warship, the Scimitar, armed with thalaron radiation, the weapon used on the Senate. Dr Crusher finds that Shinzon is dying from a flaw in his cloning, and only Picard's blood can save him. Shinzon seizes Picard, but Data, who has secretly swapped places with B-4, rescues him and learns that Shinzon intends to wipe out life on Earth.

In the Bassen Rift, where communications fail, the cloaked Scimitar ambushes the Enterprise. Two Romulan warbirds under Commander Donatra join the fight, Troi turns the Viceroy's earlier telepathic intrusion against him to track the ship, and Riker defeats the Viceroy hand to hand. With the Enterprise crippled, Picard rams the Scimitar, and Shinzon starts the thalaron weapon. Picard crosses over alone and kills Shinzon. Data follows, beams Picard back with an emergency transporter and destroys the weapon, losing his life. Back on Earth, Riker leaves to command the USS Titan, and Picard discovers that Data copied his memories into B-4, who begins to sing “Blue Skies”.
