The Boer War is finally ending and for three thieves there is the unexpected bonus of stealing an army payroll so large that they have to bury it outside a Free State town until the heat cools off. But the army choose an officer to help track them down. While the thieves wait for an opportunity to return to the stolen bounty, the officer chases them, giving rise to a riotous set of events. Based on a true story, John Harris’ adventure entertains and delights in a series of incredulous scenarios brought to glorious life against the backdrop of South Africa’s diamond mines.
