Mataura is a small town in rural New Zealand where, apart from the odd tractor theft, nothing very interesting happens. But when the body of a young mother is found washed up on the banks of the Mataura River, the small rural community is rocked by her tragic suicide. All is not what it seems, however. Sam Shephard, sole-charge police constable in the town, soon discovers the death was no suicide and has to face the realisation that there is a killer in town. To complicate the situation, the murdered woman was the wife of Sam's former lover. When Sam finds herself on the list of suspects and suspended from duty, she must cast aside her personal feelings and take matters into her own hands. She has to find the murderer...and clear her name.
