Alex Brooker and Josh Widdicombe are joined by husband-and-wife comedians Jon Richardson and Lucy Beaumont, as they experience the childlike joy of spending an access-all-areas night in Legoland. Alex, Josh, Jon and Lucy drink in some of the world's most impressive landmarks in Lego form, enrol in a high-octane race at the Driving School, and slip behind the doors of the Legoland staff workshop, where they have 15 minutes to build the most impressive Lego model they can.
