Created by Gray Hofmeyr, Isidingo explores the lives of the people of Horizon Deep Gold Mine and their wealthier counterparts at ON!TV, a fictitious 5th National Broadcaster. Pivotal to the story are the trials, tribulations, romances and passions of everyday South Africans working in the high-flying corporate world of Johannesburg, the glamorous surroundings of the television station and on Horizon Deep mine.
