The Third Doctor was unsure what was going on as his TARDIS lands inside the 25th Century to discover the First Human Empire was going to war with the Starfleet Imperium and the Vulcans for allowing the Time Lords sanctuary from the Daleks without telling anyone that they are all becoming targets because of it happening beforehand!

Fear of the Daleks had caused several Angry Crowds to try turning the Third Doctor over to the Daleks to save themselves from being killed instead.

The Third Doctor escaped being turned over to the Daleks and returned to the 22nd Century to find the Cybermen invading the Vulcans after the NX Class Starship Enterprise vanished from Starfleet History.
