I SWEAR is the inspiring, extraordinary life story of notable Tourette Syndrome campaigner, John Davidson, MBE. Kirk Jones’ emotionally engaging, funny and compelling film charts John Davidson’s Tourette’s diagnosis at the age of 15 years old. Set within 1980s Britain, the story follows him throughout his troubled teens and early adulthood, and explores this little known and entirely misunderstood condition, along with his attempts to live a ‘normal’ life against the odds.
