The story is set in present-day New South Wales, specifically during 2007 when a severe drought and water shortage gripped the region. The timing is significant because the government announced and then abruptly cancelled a plan to recycle millions of litres of water trapped in the abandoned tunnels, creating the mystery that drives the investigation.

The conspiracy centers on the NSW government's sudden cancellation of a plan to recycle water from the abandoned tunnels without explanation. The film suggests the government was covering up something related to the homeless people sheltering in the tunnels and the rumors of disappearances, with power and information potentially being manipulated to protect interests rather than public welfare.

Peter Ferguson is the producer who coordinates the expedition into the tunnels. He remains with Natasha and Steve as danger intensifies and ultimately dies from extensive internal bleeding. His death, along with Tangles' disappearance, contributes to the film's bleak and unresolved ending.
