Stardate: 46915.2 - Riker discovers that eight years ago, an exact clone of him was created when he beamed through a planet's surface while returning to his starship.

"Space, the final frontier. These are the voyages of the starship Enterprise. Its continuing mission: To explore strange new worlds, to seek out new life and new civilisations, to boldly go where no one has gone before".
In this highly successful spin-off to the original Star Trek, Captain Jean-Luc Picard and the crew of the Galaxy-Class starship, the U.S.S. Enterprise NCC-1701-D, set out to explore the final frontier. Along the way, they make first contact with myriad different species and solve reconflicts among those societies with whom they were already familiar, most notably the Klingon Empire.
