Enterprise encounters and alien probe and Picard falls unconscious. He wakes up in a different life, married to a woman he's never met. This world is dying. Picard comes to accept his new life and tries to save his new world.
One of the finest and most touching episodes of the series. Patrick Stewart shows what a fine actor he is. During the episode the viewer is left to wonder what is going on, if this is all in Picard's mind or if it is really happening. We see Picard go through stages of disbelief to final acceptance. He comes to love his new wife and world and learns to play a flute like instrument. In his golden years, Picard loses his wife and witnesses the launch of a probe into space. The ending is quite touching in that it turns out the probe installed a sort of program in Picard's mind. The purpose was to let other civilizations know that this world and it's people had existed and were now gone. Absolutely beautiful.
