It's traditionally a two-part episode for every topic. The first part is the actual- known historical context for each event. And the second part outlines the conspiracy theories that surround the event. The hosts give a personal score 1-10 of how likely they believe in the conspiracy.

The topics/ events are all the classics:
Who wrote Shakespeare's works?
Who shot jfk?
Was Mozart murdered?

Even episodes on Marilyn Monroe, Elvis, free masons, ufos, etc.

I can't think of a mainstream conspiracy that isn't covered. It's fun
