County lines dealing has pulled British teenagers into the drug trade as couriers, moving product from city hubs into small towns and coastal communities far from where it originates. The film follows the people caught inside that pipeline: kids recruited as runners, the dealers who exploit them, and the families and communities left dealing with the fallout. Interviews and on-the-ground footage trace how gangs use burner phones, coercion, and the promise of quick cash to pull minors into carrying and selling drugs, often far from home and out of the reach of parents or police. The film looks at why the trade keeps finding new recruits even as arrests and warnings pile up, and what happens to the teenagers once they are inside it, from debt bondage to violence. It is a plain, journalistic look at a spreading problem rather than a moral lecture, letting the people living through it describe the mechanics of how it works and why it is so hard to stop.
