The Missing Tesla Papers - S6.E13

Nicola Tesla is the epitome of what some would call the "mad scientist" and also one of history's most influential inventors. The father of AC electricity, Tesla had revolutionary ideas--but in the hands of the wrong people, those ideas could be used for evil purposes. When Tesla died, he allegedly had 80 trunks of papers full of groundbreaking ideas. But only 60 of those trunks have ever been seen again. Where are the other 20 trunks? What happened to Tesla's missing files... and what was in them?
