Bonanza S14 E05 Riot!

"America's Favorite TV Western"

While at the Nevada State Prison to inspect conditions, Ben is taken hostage in a riot. The riot is an attempt by frustrated inmates to expose horrific conditions at the prison. While Joe and Candy plan to resolve the situation, Ben begins a friendship with Griff King (who isn't exactly receptive), and helps communicate the inmates' demands to the warden and state prison board.
