Doctor Who

Part one

A storm rages on the planet Karn. One of the sisters finds the TARDIS buried beneath starship debris from which the Twelfth Doctor emerges requesting to be taken to Ohila.

On prehistoric Earth, the Eleventh Doctor and Alice Obiefune search for a fruit that Jenny may gift Vastra for their anniversary. The fruit Alice finds however is a nanjura fruit which, though delicious to Time Lords, is toxic to Silurians. As the Doctor snacks, a dinosaur breaks through the brush and the two start to run.

In the 24th century, the Tenth Doctor, Gabby Gonzalez and Cindy Wu travel via "space bus" through the Null Zone to Cosmomart, a planet that has been converted into a shopping mall. Despite the warnings of the pilot droid, the three transmat into the mall to find it abandoned before they are ambushed by Sontarans.

In the Powell Estate in the year 2006, Jackie Tyler flees from a mechanised dog before she is rescued by the Ninth Doctor, Rose and Jack Harkness on a flyer. Though Jackie believes the ruined state of London is the Doctor's doing, the planet has been invaded by the Cybermen. However, the Doctor believes there is more going on, as the brutal efficiency of the invasion is beyond even the Cybermen. The group's first order of business is to retrieve the TARDIS, held at the converted St Paul's Cathedral.

At Cosmomart, the Tenth Doctor surrenders to the Sontarans while Cindy lobs a shop dummy head at a soldier.
