Actor, comedian and lifelong music fan Rob Brydon travels through the southern states of America to mark the centenary of country music. He's on a mission to uncover the history of the genre - where it began, how it evolved and why it's experiencing a major resurgence, especially in the UK.

Rob heads to the beating heart of country music: Nashville. He explores iconic venues like the Ryman Auditorium, goes live on air at WSM Radio - home of the Grand Ole Opry, the world's longest-running radio show - and meets country stars old and new, including Luke Combs, Marty Stuart, Bill Anderson and rising British talent Twinnie.

In the final leg of his journey through the southern states of America, Rob Brydon explores the rich, often-overlooked influence of black musicians on the history of country music during the genre's 100th anniversary year.

In Alabama, he meets soulful vocal trio Chapel Hart, walks in the footsteps of Rosa Parks, learns about country music pioneer Hank Williams Sr from his grandson Sam Williams, has a bite at local Montgomery institution Chris' Famous Hotdogs. In Tupelo, Mississippi, he visits the birthplace of Elvis Presley, before continuing on to Memphis for a tour of the legendary Sun Studio.

Returning to Nashville, Rob joins the 9th annual Nashville Elvis Festival - a four-day extravaganza packed with Elvis impersonators from all over the world, taking to the stage for his very own Elvis tribute. He meets country music superstar Lainey Wilson to chat about the future of country music, and finally, he steps onto the stage of the Grand Ole Opry to share the story of his journey with a live audience.
