Abyss (2024) Plot Summary & Ending Explained

In the final act the collapse of the Kiruna mine forces Frigga, her two children and the men who have entered their lives to race against a widening sink‑hole that has swallowed the old town’s school. Inside the shattered building they find the teenage boys scattered on the floor, the air thick with dust and the sound of trembling rock. Simon is trapped on a precarious ledge beside the void, while Mika clings to the wreckage. Frigga grabs a fire‑hose, threads it through the debris and uses it to pull her son toward safety, but the metal pipe cuts her leg, causing her to bleed heavily.

At that moment the edge of the hole begins to give way. With the ground cracking beneath them, Frigga, Simon and Mika scramble onto a thin steel scaffold hanging from a loose cable. Tage, despite having just learned that Frigga is moving on with Dabir, throws himself onto the fraying wires, holding them long enough for his family to climb back to solid ground. The strain is too much; the cables snap and Tage is thrown into the abyss, giving his life so that his children can survive.
