Matt Baker and Ellie Harrison visit Lincolnshire, where Matt meets one of the last surviving members of the Dambusters squadron. He takes a turn in one of the few remaining Lancaster bombers and looks at how the old Dambusters airfield is being returned to nature. Ellie goes looking for a man who is two inches high and pink! The man orchid is one of our rarest flowers, but it thrives in Lincolnshire. Ellie also helps take down the sails on the only eight-sailed windmill in existence. Meanwhile, Adam is wheeling and dealing for a new white park bull, and John Craven is joined by two new celebrity judges as he launches this year's Countryfile Photographic Competition with its theme 'Animal Magic'.
