The Vault – an archive of alien artefacts securely stored deep beneath the Angel of the North.
There's also a prisoner in the Vault. An extraterrestrial known as the Master. He has been on Earth for some time, but now he's under lock and key.
This is his story.
Or, as Captain Ruth Matheson and Warrant Officer Charlie Sato discover… perhaps it is theirs.
Geoffrey Beevers (The Master), Daphne Ashbrook (Ruth Matheson), Yee Jee Tso (Charlie Sato)
