Star Trek: The Next Generation - Time's Arrow, Pt. II (Full Frame)

VHS, PARAMOUNT

After disappearing into the time distortion portal, Data's (Brent Spiner) severed head is found buried among alien ruins in 19th century San Francisco. An Away Team, sent from the 24th century, learns that the Devidians, an alien race capable of assuming human form, are traveling back in time to steal human neural energy and transfer it back to their home planet. With the help of author Mark Twain (Jerry Hardin), the Away Team concludes that the cavern where Data's head was found acts as a focusing device, enabling the aliens to put their life-sapping plan into action. As Picard (Patrick Stewart) prepares to destroy the cavern, an explosion seals him inside. Will he be forever trapped by time's arrow?.
