‘Below’ Recap & Ending Explained: The Giant Squid, the Nest and the Fate of Snook’s Arm

Netflix’s ‘Below’ is a six episode limited series that combines a creature feature premise with local folklore, family drama and a fishing town struggling to preserve its vanishing way of life. All six episodes premiered on Netflix on October 8.

The ‘Below’ recap and ending explained questions come down to a giant squid, a mysterious iceberg and a coastal community facing a resettlement vote. Jesse McKeown created the series, with Josh Hartnett as fisherman Calvin Penney, Mackenzie Davis as marine researcher Fonda Howander and Charlie Heaton as Calvin’s son, Wade. McKeown also serves as showrunner and executive producer.

The ‘Below’ Recap and the Penney Family Story

The story begins in Newfoundland in 1986, when the community of Little Pot Rock was relocated to Snook’s Arm as part of a resettlement program. The Penney family tried to float their house to the new town, but it collapsed into the ocean and took the patriarch, Leo, with it. Young Calvin caught a glimpse of something under the water before he lost both his house and his father.

Forty years later, Calvin lives in Snook’s Arm with his sister, Ruth, and his son, Wade, and earns his living through ice harvesting. When the Crocker Brewery and Distillery rejects his latest haul as unfit for human consumption, he takes it to Dr. Fonda Howander at the local Ocean Science Center. Fonda discovers that the ice is actually a mucus membrane that likely belongs to something big and ancient.

The timing is tense, since the town is in the middle of a “come home year” and a proposed resettlement program is dividing residents. Some are tempted by the financial compensation, while holdouts like Calvin keep the vote stalled. Then a giant iceberg appears in the harbor, right on the town’s doorstep.

Wade goes fishing with a rival, Jerry Biles, and the two shoot at the iceberg, which draws the attention of a creature beneath the surface. Biles dies and his ship is destroyed, while Wade survives but is badly shaken. Fonda comes to believe the culprit is a giant squid, possibly the same creature behind Leo’s death all those years ago.

Ending Explained and the Truth About the Iceberg

The iceberg turns out not to be a natural formation at all, but a mucus membrane created by the squid. Fonda first suspects it is a way of marking territory, but while evacuating samples from her laboratory she realizes the membrane is full of eggs. That makes the structure a nest.

The giant squid’s natural habitat is the Deep Arctic, but a warming ocean, thawing permafrost and melting glaciers have made it unfit for her. She drifted with the Labrador Currents and chose to stay at Snook’s Arm because her eggs were waiting to hatch. This also explains her aggression toward anyone she sees as a threat to the nest.

The closing moments are deliberately unsettling, as Calvin and his family go out to fish for ice and find more icebergs on the horizon, almost forming a wall around the Snook’s Arm sealine. The story ends before the consequences are explored, but the likeliest reading is that these are nests belonging to other creatures.

That image fits the show’s broader concerns. One reviewer points to environmental themes, including a community whose way of life is under pressure from dwindling fish stocks. McKeown told The Canadian Press that the show is about “a fisherman who can’t fish because there’s no fish left.”

Does the Giant Squid Die and Do Her Eggs Hatch

Over a few days the squid destroys nearby fish farms, kills Jerry and spreads a secretion that causes a widespread illness among residents. The army treats her as an official threat, begins a mass evacuation and prepares an airstrike. The outbreak itself is contained by Fonda and lasts only around two days.

Calvin, who opposed resettlement from the start, refuses to board the evacuation helicopter and chooses to stay and fight for his hometown. His family, along with Mary’s fiancé, Noah, and Jay’s frenemy, Mo, follow his lead. Wade and Mary fire at the nest from shore to break it apart, and Calvin hauls it away from the harbor with a giant net.

Crocker still pressures the military to go ahead with the airstrike, but the Lieutenant refuses and calls it off. The town is safe and the squid survives, though only briefly.

Most cephalopods mate only once, and the mother normally dies after the eggs hatch. In this case the water so far from the Deep Arctic is not cold enough, so the squid dies while her eggs remain unhatched.

What Happens to Snook’s Arm After the Squid

On an unplanned detour to Little Pot Rock, Calvin learns that the original resettlement was no accident. The Crocker company had discovered large reserves of copper and cobalt under the town, buried the finding and lobbied for the resettlement program. Residents were pushed out of their homes without knowing the true value of the land.

The Crockers are now trying to repeat that history in Snook’s Arm, and the airstrike would have wrecked the harbor enough to force many residents into accepting a deal. By solving the squid problem without it, Calvin protects the town from that outcome. The company still pursues legal channels, but this time the residents know what their land is worth.

Critical reception has been measured so far. One review praises the atmosphere and performances while noting that the family drama and community politics can slow the momentum, and that the series is not reinventing the creature horror genre. Another critic highlights the natural charisma Hartnett brings to the lead role.

With that wall of new icebergs closing in on Snook’s Arm just as the Crockers lose their easy excuse to level the harbor, do you think Calvin and his neighbors can hold onto their town, or is a second nest already hatching a bigger problem?
