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

Jerry Hardin had never played Mark Twain before, but he became so enamoured with the character after this that he created a one-man touring show about him. See more »


After discussing Data, Riker and Troi join Data in the turbolift, which continues on its way. However, neither of the two tells the turbolift where they want to go, as they ordinarily would, but exit with Data at his destination. While this is indeed an unusual procedure, it could be argued that Riker and Troi assumed correctly that Data was heading in their direction, i.e. the bridge, since all bridge officers had been called to their stations only moments earlier.

This episode was the fifth season ending "cliffhanger" episode and was a better one for the series finale, in my opinion. It deals with the discovery of Lt. Commander Data's severed head inside an underground cavern area in San Francisco during an excavation in 24th Century Earth. This discovery introduces the aspect of death to the android and that he doesn't have an infinite life span after all. The underground cavern emits very rare wave transmissions that could only originate from outside of Earth, so the crew becomes involved in a mystery in trying to connect the discovery of Data's head to the wave's source. They discover that aliens are using a device that allows them to go back to Earth's past and that allows them to hunt for their required energy source (which happens to be human neural energy). The Enterprise crew enters the time distortion portal in order to stop the aliens from continuing to extract the neural energy from the San Francisco populace of the 1880s. The theme of time travel has been covered in many science fiction movies and often times, there are gaping logic flaws or illogical plot twists. In this episode, there is a good plot flow and no gaping logic flaws. The only thing that does appear to be a bit flawed is when Data first appears in the 1880s San Francisco streets after entering the time distortion field. As he walks around, none of the people out in the streets take notice of him even though he looks totally different then they do (apparel and skin texture). Other than this part of the episode, this was definitely one of the better one in the series and with the "Inner Light" episode that immediately preceded it, this series reached its peak at the end of Season 5.
