Prophecy

A rescue team tracking two lost lumberjacks is nearly led over a cliff by a hound. When two men rappel down to recover the hound, they meet a gruesome fate at the hands of an unidentified creature, setting a sinister tone for the events to come.

Dr. Robert Verne, discontent with city life, accepts a job from the United States Environmental Protection Agency to investigate a logging operation near the Androscoggin River. This job becomes pivotal as it leads him to uncover troubling environmental issues.

Verne and his pregnant wife Maggie meet Bethel Isely, the director of the local paper mill, who blames the local American Indian 'Opies' for recent troubles, including the disappearance of the rescue team. The conflict between the loggers and the Opies begins to surface.

While on their way to their cabin, the couple witnesses a tense encounter between Isely's men and the Opies. The confrontation escalates, leaving the Opies' leader, John Hawks, nearly at the mercy of an armed logger, exposing the underlying tensions in the region.

During a fishing trip, Verne observes a massive salmon devouring a duck, which foreshadows the unnatural problems that plague the area. Later, a raccoon attacks in their cabin, leading Verne to send its tissue sample for testing, hinting at potential contamination.

Hawks and his wife Ramona approach Verne to shed light on the Ill effects their people are suffering from, warning him about a malevolent presence. It becomes clear that the environmental destruction has unleashed more than just ecological disturbances.

Verne and Maggie tour the paper mill to find evidence of pollution but are assured the chemicals remain contained. Upon leaving, Verne discovers mercury on Maggie's boots, leading him to suspect severe contamination that could explain the illnesses plaguing the Opie community.

The Nelson family, camping in the woods, faces a horrific attack from Katahdin, a mutated bear. Paul Nelson’s desperate attempt to escape ends fatally, igniting a desperate need for Verne to protect those around him and investigate further.

As Verne attempts to collect blood samples from the Opies, a misunderstanding leads to the arrest of Hawks and his men. This pivotal moment causes tensions to rise and pushes Verne deeper into the crisis as he strives for the truth.

After witnessing the aftermath of Katahdin's attack, Verne and his group seek refuge at Hector's home. As the mutated bear threatens them, they must navigate a spiraling situation filled with danger and uncertainty.

Amidst the growing chaos, Maggie reveals to Verne that she is pregnant and has consumed contaminated fish. This shocking revelation raises the stakes as they confront the implications of environmental destruction on their future.

Katahdin attacks the group gathered at Hector's home, resulting in chaos and death as they try to find safety. The creature's ferocity escalates, resulting in lives lost and the tension building within the remaining survivors.

As the survivors attempt to flee the forest, they face numerous obstacles including a brutal encounter with Katahdin. In a critical moment, Verne must make a harsh decision to drown a bear cub, revealing the ferocity of their survival instincts.

In a desperate final confrontation, Verne manages to wound Katahdin with gunfire and arrows. The fight escalates until Verne delivers the final blows, bringing the beast down into the lake, but not without loss and tragedy for those who remain.

The following day, Verne and Maggie escape the horrors of the forest by air. However, uncertainty looms as another mutant creature might still reside within the wilderness, leaving their future uncertain and the threat unresolved.
