The Enterprise sets out to help the colonized planet Penthara IV, where an asteroid impacts with an apocalyptic effect, first scorching then lasting clouding comparable to nuclear winter. On the route to it, an unknown vessel appears after a temporal distortion and beams aboard history professor Berlingoff Rasmussen from earth three centuries later (the 26th), who is obsessed by Picard, who accepts the whole crew to be questioned, despite the possibilities of fraud or altering reality. Once at Penthara 4, Geordie down there and Data aboard devise a method to create a greenhouse-effect, at the risk of making it far worse, so Picard wrestles with using Rasmussen's hindsight, but his own history proves significantly problematic...

Two of the pieces of classical music simultaneously listened to by Data in this episode were heard again in later Trek episodes. The Third Brandenburg Concerto was later played by Captain Picard on his Ressikan flute and "La donna è mobile" was regularly sung by The Doctor on Voyager. See more
