Cold War

Written by Mark Gatiss

"It's an Ice Warrior. A native of the planet Mars. And we go way back. Way back."

The Doctor and Clara land on a damaged Russian Submarine in 1983 as it spirals out of control into the ocean depths. An alien creature is loose on board, having escaped from a block of Arctic ice. With tempers flaring and a cargo of nuclear weapons on board, it's not just the crew but the whole of humanity at stake!
