After graduating university, four friends - Peter, Avery, James, and Isaac -- spent a golden summer working in a vineyard. Years later, Peter is brutally murdered in Martinborough. Meanwhile, north of Auckland, the long, hot summer is over and the tourists have left Matakana wine country. A tranquil atmosphere descends, and warm autumnal winds sweep across the valleys. With the harvest due, grapes sit bursting upon the manicured vines, awaiting the pick. Then a severed hand is discovered under Avery's house. It's Peter's. Within this vista of peace, a rampage of death is about to rock the local community to its core. Will the four friends be picked off one by one? And is something in their shared history behind the killing?
