Joan is a British filmmaker who embarks on a personal journey to explore the country's colonial past. The film is shot over a decade and follows Joan as she investigates the impact of Britain's colonial history on modern-day society. Along the way, she meets with historians, politicians, and activists to discuss the lasting consequences of colonialism and its effects on race relations in the UK.
As a person of mixed heritage, Joan also reflects on her own experiences growing up in a society shaped by colonialism. She grapples with questions about identity, belonging, and cultural heritage, and explores the ways in which her racial background has influenced her life and sense of self.
Through interviews, archival footage, and personal reflections, That Great British Documentary offers a nuanced and thought-provoking examination of Britain's colonial legacy, as well as its impact on individuals who continue to grapple with its complexities today.
