Netflix's Below Exposes Mining Plot and Threatens a Darker Future

A secret mineral extraction plan and the ecological consequences of warming seas drive the final episode of Netflix's six-part thriller Below, as fisherman Calvin Penney, played by Josh Hartnett, confronts a giant deep-sea creature threatening Newfoundland's Snook's Arm. The finale reveals that the evacuation could benefit a powerful business family while offering a different explanation for the animal's aggression.

According to TIME's October 8, 2026, analysis and Decider's October 10, 2026, ending breakdown, the creature's behavior is connected to an iceberg carrying its egg sac. Marine biologist Fonda Howander, played by Mackenzie Davis, discovers that the animal is protecting its offspring in water that has become too warm for them to survive.

The revelations connect the town's immediate danger with a longer-running dispute over its land. The Crocker family has pushed to relocate residents, while a mining permit bearing the family name points to deposits of cobalt and copper beneath Snook's Arm.

TIME identifies the permit as a pivotal discovery in the penultimate episode. Decider adds that the company's operations in other resettled communities allowed it to pursue valuable minerals without negotiating fair compensation with local residents.

In the finale, Calvin and his son Wade, played by Charlie Heaton, develop a plan to move the iceberg away from the community. They reduce its size and tow it into deeper water, allowing the creature to follow them away from populated areas rather than face a military bombing operation.

Calvin's decision marks a shift in his understanding of the animal. The creature that he associates with his father's death is also a mother attempting to protect its young, complicating the assumption that it is simply a threat that must be eliminated.

Series creator Jesse McKeown described Calvin's changing perspective to TIME as central to the story's resolution.

"The whole story has been a kind of slow awakening for Calvin. That's what the finale is: eyes wide open. What are you going to do now?" McKeown said.

After surviving their escape from Little Pot Rock, Calvin also acknowledges his mistakes as a father. He thanks Wade for saving his life and recognizes that he underestimated his son's abilities as a fisherman.

"You and me had a hard go of it since your brother and your sister left, and your mother before that," Calvin tells Wade.

He then admits that keeping his son away from the boats was wrong.

"I should never have kept you off those boats. You'd have made a fine hand. I can see that now," Calvin says.

Heaton described Wade's early characterization as a "lost boy" with "all this energy" but little direction. The actor said Wade's eventual acceptance by his father gives the character a meaningful change after much of the season portrays him as struggling to find his place.

"To finally be trusted, I think, is a big thing," Heaton said.

Hartnett told TIME that Calvin's fear had damaged his relationship with his son.

"His fear was holding him back and making Wade the person that Calvin was upset he became," Hartnett said.

Meanwhile, the Canadian military prepares to remove residents from the shoreline because of the danger posed by the creature. A lieutenant overseeing the evacuation acknowledges that his forces have limited capacity, with wildfires also burning in western Canada.

He describes the military as "spread too thin." During the evacuation, Jim Crocker introduces his daughter Jan, played by Natasha Henstridge, as the business family's interests intersect with the emergency response.

Fonda's scientific findings challenge the military's plan. She identifies the animal as an unusually intelligent, female deep-water cephalopod and explains that the iceberg contains its developing offspring.

"Her egg sac is frozen in that iceberg out there," Fonda says.

She warns that the conditions threaten the eggs, rather than suggesting the creature is attacking without cause.

"These waters are too warm for her. Her eggs won't survive, and she knows it," Fonda says.

Fonda argues that the creature should be examined instead of destroyed, particularly because it may represent a species with no known surviving counterparts.

"to be studied, not bombed from the sky," she insists.

A soldier counters that the danger has already resulted in significant losses.

"Respectfully, this thing has downed three vessels and killed 19 people so far," the soldier says.

He maintains that the military must act to protect people in the area.

"We have a duty to eliminate the threat," he says.

Jim Crocker offers Fonda exclusive access to the creature's remains after it has been "dealt with." He uses the possibility that the animal is rare to support his offer, telling her, "She may be the last of her kind," even as his family's financial interests remain central to the conflict.

Davis told TIME that Fonda's eventual response reflects the difficulty of ignoring evidence once it becomes impossible to dismiss.

"It's easy to turn a blind eye to it until it's placed very baldly in front of you," Davis said.

The actor explained that Fonda had previously "convinced herself she was doing that before" while remaining "pleasantly ignorant." Her approach to the creature is grounded in scientific curiosity rather than revenge.

"She's moving through this whole experience with curiosity rather than vengeance," Davis said.

The ending does not offer a straightforward survival story for the animal. According to Decider, the giant squid dies after reaching deeper water, with its body providing nutrients to its offspring as they prepare to hatch. The young briefly swim away, but Fonda warns that rising water temperatures threaten their chances of survival.

"And it's just getting warmer," Fonda tells her assistant.

She follows the warning with a broader concern about future environmental changes.

"And who knows what's next?" Fonda says.

A year after the main events, Snook's Arm has become a tourist destination, with businesses benefiting from public interest in the creature. Fish have also returned to the surrounding waters, according to Decider's account of the final scenes.

The apparent recovery does not last as a reassuring final image. Calvin and Wade see a fleet of icebergs approaching, raising the possibility that other deep-sea creatures could reach the region under similar conditions. The toxic secretions associated with the original creature can cause severe dehydration and eventually madness, while the approaching ice suggests the danger may extend beyond one animal.

Decider notes that the series leaves several storylines available for further development, including the Crocker family's influence, Wade's relationship with Maggie, and unexplained elements surrounding her possession of an engagement ring intended for his sister Mary.

However, the publication reports that Hartnett said there were no plans for a second season. Netflix presents Below as a limited series, and the finale leaves its characters facing an uncertain environmental threat without confirming that another installment will follow.
