Joe Crowley is on the west coast of Scotland, celebrating a local delicacy — the oyster! Every year, people flock to the small coastal town of Stranraer to visit the Stranraer Oyster Festival, where people come together to celebrate these very special shellfish. Joe meets the people behind the festival and finds out why this event has put Stranraer back on the map. He sails out onto the sparkling waters of Loch Ryan to discover how the fisherman harvest oysters with sustainability at the forefront. Over a campfire, Joe is shown how to cook a simple oyster dish by chef Pam Brunton and meets the competitors of the weekend's biggest event — the shuck-off! Meanwhile, Adam Henson is in the Cotswolds, welcoming two new additions to the farm.
