The United Nations Intelligence Taskforce (UNIT) scientist, is kidnapped by Zygons, and will need the help of Clara and Doctor to get free, according to Christian Today.

Notably, the Zygons have been featured on the iconic sci - fi series since  1975, and the most recent appearance was in the 50th anniversary episode.

They had initially planned to invade the Earth, as their planet was destructed, but failed due to the intervention of Time Lord and his companions, according to International Business Times.

Additionally, the second part of the Zygon oriented episode will be more deadly as showrunner Steven Moffat has revealed that the trusted companion of Doctor will be missing from action.

Although the plan of Zygons has been good, yet confusions arise as to how a dead girl can be kidnapped again. This is because, in Season 8, when Osgood last appeared, Missy (Michelle Gomez) vaporized her.  Thus, viewers are in confusion if Osgood had survived the incident or not.

Perhaps, fans of the series will have to tune into the Halloween episode of "Doctor Who" in order to get the answers.

The two part Zygon special episodes will air on BBC America on Oct. 31, and Nov. 7 respectively at 9 p.m. EDT.
