When forest protests engulf a tiny Tasmanian timber town, one family's century of secrets threatens to destroy a marriage - and bring down a government. Matt Abbott, head ranger at beautiful Binburra National Park, is a man with something to hide. He confides his secret to nobody, not even his wife Penny. The deception gnaws away at their marriage. Matt's father, timber and mining magnate Fraser Abbott, stands for everything Matt hates. Son disappoints father, father disappoints son - this is their well-worn template. But Fraser seems suddenly determined to repair the rift between them at any cost, and Matt will discover that secrets run in the family. When Sarah, a visiting Californian geneticist, tries to steal Matt's heart, the scene is set for a deadly betrayal.
