Long before the circus lights and thunderous applause, there was a boy named Phineas — poor, sharp-witted, and filled with vision. In this premiere episode of The Cavern, we step behind the curtain to uncover the life of P.T. Barnum. Not the myth. Not the movie. The man. From Joice Heth to Tom Thumb, from controversy to compassion, discover how Barnum turned sideshows into second chances — and built a stage where the world’s misfits could shine.
