A terrifying tale of survival in the mangrove swamps of Northern Australia.

A search and rescue team are transported through deep space to a distant mining colony to save the sole survivor of a biological outbreak. During their mission, they find a lethal weapon which is set to arrive on Earth within the hour.

In 2007, in the midst of the drought and water shortages, the NSW State government has unveiled plans to tap into and recycle millions of litres of water trapped in a network of abandoned train tunnels just beneath the heart of Sydney. However the government suddenly goes cold on the plan and it is not made public why. There is talk of homeless people who use the tunnel as shelter going missing, even though the government states that there are no homeless people in there. This, and the silence from the officials and ministers, leads a journalist, Natasha to begin an investigation into a government cover-up. She and her crew Pete (Producer), Steve (Cameraman) and Tangles (Sound Technichian) decide to investigate the story in the tunnel.
