This film explores why mistrust in healthcare research exists and how under-representation fuels inequality. Through honest accounts from experts, community champions, and participants — including Dr Chris van Tulleken — it highlights challenges such as sickle cell disease, youth mental health, and complex needs. Filmed in north London, the stories point to pioneering initiatives, good practice in EDI, and a clear call to action: building trust and raising awareness of Be Part of Research.
