Ace is back. And she is not in a good mood.

Bernice has asked the Doctor to bring the TARDIS to the planet Lucifer, site of a scientific expedition. It's history to her: the exploration of alien artefacts on Lucifer came to an abrupt halt three centuries before she was born, and she's always wondered why.

Uncovering the answer involves the Doctor, Bernice and Ace in sabotage, murder, and the resurrection of eons-old alien powers.

Are there Angels on Lucifer? And what does it all have to do with Ace?

Not men, Ace. Silurians. The original rulers of the Earth.

The TARDIS is attacked by an alien force; Bernice is flung into the Vortex; and the Doctor and Acecrash-land on Earth.

An attack by dinosaurs convinces the Doctor that he and Ace have arrived in the Jurassic Era. But when they find a woman being hunted by intelligent reptiles, he begins to suspect that something is very wrong.

Then they meet the embittered Brigadier Lethbridge-Stewart, leading the remnants of UNIT in a hopeless fight against the Silurians who rule his world. And they find out that it all began when the Doctor died...

"Change, Benny. It's the most terrifying thing of all."

"And that's what's happening to you, is it, Doctor?"

"It's what's happening to all of us."

With the members of one expedition murdered, those of another fighting for their lives and a solar system on the brink of civil war, can the Doctor, Ace and Benny survive a journey to the heart of the Artefact in their search for the truth?

"The flood is come! Oh God save us all; the day of judgement is come!"
