“Nikola Tesla dreamed up the twentieth century before it happened!”

  1. On the edge of Niagara Falls, something is wrong at Nikola Tesla’s generator plant. Who or what is sabotaging the maverick inventor’s work? Has he really received a message from Mars? And where does his great rival Thomas Edison fit into these events?

The Doctor, Yaz, Ryan and Graham must join forces with one of history’s great minds, to save both him and planet Earth.
