Joe Rogan wears a lot of hats -- stand-up comedian, podcast host, and mixed-martial-arts broadcaster among them -- but it's a tin-foil hat that he wears in this unscripted series, as he looks to uncover the truth behind various theories and mysteries. He travels across the country, questioning any "expert" he can locate, in order to find out the truth that he seeks. Nothing is off-limits in his quest for answers. Some of the topics Rogan tackles include the existence of Bigfoot, killer man-made viruses, and the possibility of weaponized weather.
