The story follows Grace (Diana Glenn), her husband Adam (Andy Rodoreda), and her younger sister Lee (Maeve Dermody) as they embark on a fishing trip in the mangrove swamps of Northern Australia. Seeking a relaxing day out in nature, the group hires Jim (Ben Oxenbould), a local guide, to take them to a secluded spot for fishing. The serene atmosphere is soon disrupted as their small boat is capsized by a massive saltwater crocodile.
As Jim is dragged underwater and killed by the predator, the remaining trio manages to climb a nearby tree, out of the crocodile’s immediate reach. Stranded in the middle of the swamp without any means of communication, they are forced to grapple with the reality of their situation. The crocodile lurks menacingly in the water below, leaving them terrified and unsure of how to escape.

The film intensifies as the group attempts various strategies to survive. They face not only the external threat of the crocodile but also internal struggles as fear and desperation begin to take their toll. Adam tries to swim to retrieve the capsized boat but meets a tragic fate, leaving Grace and Lee to fend for themselves.
Grace, determined to save her sister and herself, displays incredible resilience and courage. The film poignantly explores themes of survival, the fragility of human life, and the indifference of nature. The claustrophobic setting of the swamp, combined with the ever-present danger of the crocodile, creates an atmosphere of unrelenting tension.

The use of practical effects and real crocodiles adds authenticity to the film, making the predator feel genuinely threatening. The naturalistic performances of the cast and the immersive cinematography effectively convey the terror and isolation of their ordeal.
Black Water is not only a nail-biting survival thriller but also a testament to human endurance in the face of overwhelming odds. Its minimalist approach and focus on character-driven tension make it a standout entry in the genre, leaving viewers with a lingering sense of dread long after the credits roll.
