Diamonds are a girl’s best friend.

Joan Hannington was the most notorious female figure in London’s criminal underworld during the 80s, earning her the nickname ‘The Godmother’. With her stunning looks and glamorous wardrobe, Joan was constantly underestimated, but she used this to her advantage and became an undetected mastermind in high-stakes jewellery theft. Often transforming herself into different characters, Joan seamlessly got away with millions of pounds in diamonds.

Coming from a violent, loveless childhood, Joan learnt to trust no one but herself. At seventeen, she becomes a mother, but is trapped in a disastrous marriage with a brutal thug. When he goes on the run, Joan seizes the moment to leave her old life. Motivated by her desire to care for her daughter, Joan gets swept up in the exhilarating world of a life of crime and makes some heartbreaking decisions as she sets her sights on a better life.

Joan is the true story of her meteoric rise from petty offender to one of Britain’s most accomplished diamond thieves, making a success of life by not playing by the rules when the odds seemed stacked against her.
