Synopsis
Each episode typically dealt with an event or subject in history that is not completely understood by modern historians. As such, many of the topics covered are controversial in some respect. Josh Bernstein usually mentioned the various theories that exist on the subject, although the episode may not actually have explored all of them. He then traveled to various locations to ask questions of researchers, and he often he put himself into situations (e.g. working in a quarry, climbing a rock-face) that simulated the activities of people in the time period he explored. Almost all of the researchers he talked to were professionals in the subject at hand, and many of the places he visited (e.g. the inside of a pyramid) are not open to the general public. At the end of the each episode, Josh pulled together everything discussed in the episode to either formulate a hypothesis of what actually happened historically or to conclude that what really happened remains a mystery.
