Eighth-generation Tasmanian and environmentalist Oliver Cassidy embarks on a life-changing solo rafting trip down the Franklin River. His goal is to retrace his late father's 14-day expedition to attend the blockade that helped save the World-Heritage listed national park from being destroyed by a huge hydroelectric dam project in the early 1980s. Featuring never-before-seen archival footage and interviews with key players such as Bob Brown and Uncle Jim Everett, the eight-year-long 'Franklin campaign' is revealed as the most significant environmental protest in Australia's history; an inspiring example of the power of non-violent direct action to bring about lasting change.
