A strange voice is interrupting TV broadcasts across the capital, and bear-like creatures are raiding factories, stealing equipment and killing guards. The Great Intelligence and his army of Yeti have returned. And there’s only one team that can stop them.

Familiar with their foe, Sir Toby calls on the help of Edward Travers to defeat the menace. But without the Doctor to help them, can the Intelligence ever be stopped?
