Documentary following the emotional journeys of six people as they attempt to gain control of their stammers. A lorry driver, a teacher, a pharmacist, a professional photographer and two schoolboys have all agreed to undergo a course that claims it can transform a stammerer's speech in just four days. The McGuire Programme is an intensive and emotionally-charged residential course run by former stammerers, using physical and psychological techniques, which can lead to life-changing results - but is not for the faint-hearted.
