Si and Dave visit Bomber County, Lincolnshire, on a mission to discover the importance of the county's pubs during World War II. They visit a boozer that housed the homeless when the village was bombed and meet veterans with tales of daring do. And in Woodhall Spa, they visit the Bluebell Inn, a pub that served the famous Dambuster Squadron, amongst others, and now stands as a living memorial to all the veterans who served from the nearby airbase.
