In April 1999, one of Britain’s most celebrated and loved television presenters and newsreaders, Jill Dando, known for her work on the Six O'Clock News, Crimewatch and Holiday, was shot and killed on the doorstep of her home in the middle of the day. It was a crime that reverberated across the country, from the millions of television viewers used to seeing Jill in their living rooms, all the way up to the heart of government - even the Queen commented on Jill’s death. Now, ahead of the 20th anniversary of her murder, this film tells the full story behind one of Britain’s most high-profile unsolved killings, as told by the people at the heart of the case.

To celebrate her 80th birthday, the Queen is holding a children's party in the grounds of Buckingham Palace. She has invited many classic characters from British children's literature. But when the baddies, led by Cruella de Vil, discover that they have not been invited, they steal the Queen's handbag containing her spectacles and the text of her speech; without it, the Queen will not be able to make a speech at the party. Can the goodies find the handbag in time?
