A young Londoner who joined a gang when he was 14 has made a film to teach others not to make the same mistake.
Dante Powell-Farquharson is showing the movie, which has a comedy twist, to teenagers in schools around London.
He suggested the idea to a campaign called Fixers. They gave him the time, the equipment and the expertise to tell his story to you.
Fixers is a movement of young people tackling issues they feel strongly about to make a difference to others.
The ‘Fixers’ are young people who want to change things for the better.
Many have been through difficult times, and have used that experience to campaign on issues that matter to them, like being homeless, domestic abuse, or drink and drug misuse.
As part of their campaigns, and working with professional producers, they've created some fantastic films, songs, music videos and other resources. Several have won awards.
