Champions of the Lost Causes podcast host Marvin Stockwell -- along with his daughter Vieve and his son Cormac -- will crisscross 17 states in five weeks this summer to document stories of people changing the world by championing causes.

"In my first 40 episodes, I've come to feel a real kinship with the people I've had on the show," Stockwell said. "Most of those episodes have featured people in my hometown of Memphis. I've interviewed a handful of people in other cities over Zoom, but nothing can replace face-to-face interaction and seeing the work first-hand. I thought it was time to see what’s happening in the rest of the country."

Stockwell began the podcast in 2019 to take his curiosity beyond his own civic cause – saving and reopening Memphis' shuttered Mid-South Coliseum.

"I first got curious about why I had the fire in the gut," said Stockwell, who began writing the full-length book, Champions of the Lost Causes, in 2018. "I wanted to get another lens on why people champion causes and learn from their experiences. This road trip is an extension of that."
