18 months after the Taliban takeover of Afghanistan, File on 4 hears from people still stuck in hiding; their names blacklisted because of the work they did for the British.

Following the fall of the country and the frantic evacuation, the UK Government made a series of promises not to leave behind those who'd helped the UK.

The programme investigates the failures of these schemes, which have seen tiny numbers getting to safety in the UK. Thousands more left living in fear, facing torture and kidnap have been left languishing for months without contact or support.
