"These two people are here. They appeared in the tunnel, which we know
is inescapable, and are now trapped down here with us.”
It's been seven months since the attack at the bank. A bank clerk, an assistant manager, an alien security guard and a homeless man find themselves trapped in an inescapable tunnel underneath the bank vault.
There is no way out.
And then a mysterious silver-haired man arrives with a young girl. The Doctor and Mary claim to come from another planet.
But is there something else going on here? Something that goes far deeper than a simple attack on the Hallean home world?
This is the second in a series of ongoing adventures for the Doctor (Sean Pertwee) and Mary Auckland (Antonia Clarke)
