For hundreds of years the bones of Aboriginal women and their half cast white babies have lay buried beneath sand in caves on Hindmarsh Island, South Australia. Hiding these women's shame was called "Secret Women's Business." Ben Hood is hired to protect a white woman and her adopted Aboriginal teenage daughter who live on a property fronting the mighty Murray River on Hindmarsh Island. Death threats have been made against the woman by her ex-husband. A previously employed bodyguard was allegedly killed by a shark in the Murray River. Ben discovers that lies were fed to the Coroner as to the death of Ben's predecessor. "Secret Women's Business" can also be used to mask more recent murder. The more Ben pokes his nose into this, the more likely it will be that he may not get home alive.
