Actor and film-maker Noel Clarke grew up in west London with his single-parent mum, and this left one side of his family tree a mystery to him.

His search starts in Trinidad, where both his parents are from, but soon takes him on a trail to other islands, ending on one of the smallest and most beautiful in the Caribbean. There he learns of an extraordinary great-great-great-great-grandfather called Glasgow Bedeau, who was born into slavery. The music Glasgow's enslaved parents and grandparents passed down reveals the part of Africa from which Noel's ancestors were taken.
