Bond of Blood is a modern version of the biblical story of the prodigal son. It tells the tale of a father, David, who owns a wine farm in Stellenbosch, and his two sons. The younger son, Luke, an aspiring stock trader, wants to get out of farming and move to the city. To do so, he needs money and asks his father for half of his inheritance. The older son, Chris, is passionate about the farm and the wine that they produce. The younger son leaves for Johannesburg where he subsequently squanders all his money on gambling, alcohol, drugs and general bad decisions. He ends up homeless, living on the streets. He finally comes to his senses and decides to return home. His father and mother welcomes him back with open arms and forgives his transgressions. The older brother, who had remained on the farm, resents the mercy shown. In the end, the older brother forgives the younger, and allows him to work on the farm.
