MI High - Series 1 - The Power Thief

Children's spy drama. When freak power cuts sweep the nation, the teenage spies are in the dark about who or what is to blame. A mysterious voice transmits a ransom demand: pay up or Britain will be sent back to the Dark Age. Blane thinks there is some truth in Stewart's hairbrained theory that ley lines are sucking away electricity. But Rose is unimpressed by Blane's hocus-pocus ideas.
