A clandestine 'tunnel party' in the depths of the hinterland draws kids from all over the area with the usual fare of sex, drugs, and thumping music, but mostly with the lure of a spectacular stunt--that then goes awesomely awry. As fire spreads through the bush, cops descend, and the teens flee onto the dark roads in panic, the crash that follows becomes the transformative event that drives the main characters and the mystery of the show. The crash is an end-point for some and a catalyst for others, forging new alliances and triggering events that transform their lives and the idyllic town.
