At their crocodile-infested campsite, Sara urgently wants to move the group to safety, but her husband Tom and his sister Diane mock her fears as an overactive imagination. The conflict escalates when their young son, Duke, uses bloody bait against Sara's warnings, causing a family argument where Sara is isolated and told she needs help. The turning point comes when Tom, fed up, tells Sara to leave with their daughter Lily if she's so scared, forcing her to choose between staying in danger or trying to escape alone. As Duke runs off excitedly to fish, a terrified cry pierces the air, leaving the family's fate suddenly uncertain.
