An investigation into a government cover-up leads to a network of abandoned train tunnels deep beneath the heart of Sydney. As a journalist and her crew hunt for the story it quickly becomes clear the story is hunting them.

Two young Australians decide to go on an adventure to become the first to cross Victoria Island unsupported. Alone and high in the Canadian Artic, to say it doesn't go to plan is an understatement.

THE TUNNEL is hands down the greatest Australian found footage feature and this tenth anniversary documentary not only gives you a look behind-the-scenes at the production of the film, but also insight into its impact and enduring legacy.
