Black Water (2007) is an Australian survival horror thriller directed Andrew Traucki and written by John Ridley. Set in the remote wilderness of Northern Australia, the film is based on a true story and explores the harrowing experience of three people who find themselves trapped in a swamp with a giant, aggressive saltwater crocodile hunting them. The film’s grounded approach, realistic tension, and minimalistic narrative make it a gripping exploration of human survival against nature’s most terrifying predator.

The story of Black Water revolves around three tourists—Grace (played by Diana Glenn), her boyfriend Adam (played by Andy Rodoreda), and her sister Lee (played by Maeve Dermody)—who venture into the Australian wilderness for a sightseeing trip. While on a boat tour through the mangrove swamps, their guide Jim (played by Ben Oxenbould) unexpectedly encounters a saltwater crocodile. The situation quickly escalates when the crocodile capsizes their boat, and the group is left stranded in the water with the massive predator lurking nearby.

What follows is a tense, survival-driven journey as the group attempts to escape the relentless creature and find safety. As they move through the swamp, they realize the severity of their situation—no rescue is imminent, and every step brings them closer to danger. They are forced to confront the overwhelming fear of being hunted by a predator far more powerful and dangerous than any they’ve encountered before.
