Lt. Commander Geordi La Forge is in love but too timid to talk to Christy Henshaw. When a space ship's escape pod is found crashed on an uninhabited planet, he is part of the landing party and has his brain connected by Dr. Crusher to the injured sole traveler, but 'John Doe' makes a massive contact and soon recuperates physically at amazing speed by mysterious cell structure mutations. He has amnesia and by instinctively touching a wounded patient proves able to heal instantly. Geordie and Data examine an unusual memory storage capsule from the pod, which allows estimating his origin, but he refuses to return, and causes his powers to manifest themselves differently. At approach, his home planet Zarkon demands his extradition as escaped criminal, to be executed... Written by KGF Vissers

Did You Know?


A large transparent interface seen on the bridge of the Zalkonian warship was previously seen on the surface of Risa in the teaser of Star Trek: The Next Generation: Captain's Holiday (1990). A second display that is seen behind the Risian one first appeared in Picard's alternate ready room in Star Trek: The Next Generation: Yesterday's Enterprise (1990) and would later reappear in Benjamin Maxwell's ready room aboard the USS Phoenix in Star Trek: The Next Generation: The Wounded (1991).

Who is John Doe?!
17 November 2014 | by MartinHaferSee all my reviews

An escape pod has crashed onto the planet below and the Enterprise investigates. The being inside is near death--yet, inexplicably, he survives. Not only that, but his body has amazing recuperative powers--and without this he never would have pulled through. Additionally, there is something about the guy that makes those around him really like him...including the Doctor. At the same time, the once shy Geordi suddenly is a hit with the ladies...all this following his being linked, briefly, with the alien. Who is he and how does he have such powers? When asked, this John Doe says that he has no idea who he is. Who is this being really and what sort of agenda does he have, if any? And, from whom was he escaping when they found him?

Apart from the annoying plot element where John couldn't remember anything until the very end of the show (and there was no explanation for this), this isn't a bad episode. On the other hand, almost all the episode was aboard the ship and the ending was a bit too 'nice' for my taste. Overall, watchable but weak.
