Four friends, a shared past, a common enemy. In New Zealand's Martinborough, an ex-wine maker is murdered. The precise planning and execution by the unknown assailant begin a series of vile attacks. Meanwhile north of Auckland, the long, hot summer is over and the tourists have left the Matakana wine country. A tranquil atmosphere descends and warm autumnal winds sweep across the grape-laden valleys. With the harvest due, grapes sit bursting upon the manicured vines awaiting the pick. Within this vista of peace, a rampage of death is about to rock the local community to its core. Will it be their shared history that sees the four friends being picked off one-by-one?
