Documentary recorded for the 40th anniversary, revealing the true character of those working behind and in front of the camera on Britain's longest continuously running children's programme. It charts Blue Peter's evolution from a hobbies show about dolls and trains to the BBC's flagship children's programme, and discovers how Blue Peter was very nearly taken off air. Presenters of every Blue Peter generation give candid accounts of what it was like to work on the programme, and the editors past and present fight back at critics who say the show was too middle class. Narrated by Juliet Stevenson, the programme questions whether Blue Peter still has a future in the multi-channel digital age and sets the record straight on the missing Blue Peter presenter who until now has been written out of the BBC archives.
