-------------------

Plot
On stardate 45635.2 (falling between the stardates of The Next Generation episodes "The Outcast" and "Cause and Effect"), the Federation planet Delta IV comes under attack from a combined force of Borg and the Cybermen who were first seen in Rise of the Cybermen. This prompted a planetary evacuation.

Meanwhile, the TARDIS, with the Eleventh Doctor, Amy Pond, and Rory Williams inside, somehow crosses between universes and lands on the holodeck of the Enterprise-D. Though confused at having new memories from this universe, the Doctor meets with the ship's captain, Jean-Luc Picard, and they soon discover the Borg/Cybermen alliance. However, the Cybermen quickly turn on the Borg, prompting the Borg to ask Picard for assistance, to which he reluctantly agrees. Among the new memories the Doctor recalls is how his fourth incarnation encountered an earlier generation of Cybermen alongside James T. Kirk and his Enterprise.

The Enterprise crew begins work on adding gold to its weapons, since it is effective against Cybermen, while the TARDIS goes back in time to retrieve a vital piece of Borg technology that had been lost to the Cybermen. A strike force led by the Doctor and Picard then infiltrates the Cybermen's main vessel and, with the help of the Enterprise's gold-enhanced weapons, defeats the Cybermen. The Doctor and his companions return to their own universe aboard the TARDIS; meanwhile the Borg, intrigued by the Doctor, decide to investigate time travel.
