After a joyous wedding between William Riker and Deanna Troi, Captain Picard and the Enterprise crew stumble upon a mysterious signal which results in it being a prototype android who is the twin to Data. Then the Enterprise is invited to Romulus to negotiate peace with the Romulans by their new Praetor named Shinzon. However, Shinzon is revealed to be a clone of Picard who was raised on Remus, a slave planet to the Romulans. Later on, Picard discovers that this peace treaty was nothing more than a set-up due to the fact that Shinzon needs Picard in order to survive. But little do the Enterprise crew know that Shinzon also plans to do away with the Federation by unleashing a weapon that could destroy a whole planet.
