Picard and the Enterprise are urgently called back to Earth to see the results of an archaeological dig that reveals aliens may have visited the planet in the 19th century. Among the many relics they have found is one that is totally out of place - Commander Data's head. Data confirms that it is his own head and not that of his brother Lore. He seems completely at ease with the find, which is not the case with the rest of the crew. On the planet, Data encounters a temporal vortex and he suddenly finds himself transported to 19th century San Francisco where he meets none other than Guinan. Written by garykmcd

Did You Know?


Executive producers Michael Piller and Rick Berman had at first not wanted to end Season 5 with a cliffhanger. But they changed their minds when Star Trek: Deep Space Nine (1993) went into production at this point. Piller remarked: "Because of all the attention DS9 was getting and the rumors that TNG was shutting down, we wanted to send a message that the show was alive, well and continuing to grow."

It's All in Data's Head
6 September 2014 | by (United States) – See all my reviews

The Away team goes to a cave that had not been investigated for 500 years. In it they find a broken watch, a few other artifacts, and, most amazing of all, a tarnished and broken metallic head, that of Commander Data. Apparently, this head has been there all this time and is evidence of some intergalactic invasiveness into this century. Since Data is now alive, something must be done. In a delightful first half, Data finds himself in San Francisco around the turn of the century. He is so out of place, but it is San Francisco. He needs money and gets into a poker game. He rents a room and begins to build a device to go after a couple of time traveling cannibals. Along the way he runs in to Samuel Clemens and a young Jack London. He awaits the arrival of the rest of the crew to assist his efforts. Of course, there are numerous complications, among these the constant meddling of Clemens who believes there are aliens and they are up to no good.
