Australia, 1967. The Doctor, Ace and Group Captain Gilmore’s Counter-
Measures Group investigate after members Allison Williams and Rachel
Jensen discover an alien spaceship at a nuclear test site.
Meanwhile, in 2029, Group Captain Gilmore is found in space, in
suspended animation… Back in 1967, Gilmore’s assistant, Delafield,
kills a strange snake-like entity attached to civil servant Pendry –
killing Pendry in the process. When a severe storm hits the ICMG’s
camp, Delafield and Jonquil Sharrow kidnap Allison and Rachel,
leaving the others behind – but the Doctor engineers a speedy escape.
With Ace’s assistance, he makes contact with the “snakes” – in
reality, friendly aliens on the hunt for deadly-but-beautiful
adversaries who have secretly engineered human history of their own
ends for millennia. Now, with Allison and Rachel in danger, can they
and their allies prevent a global nuclear disaster?
