Flying dark, a plane carrying a team of mercenaries crash-lands on a remote snowy summit. When they come across a mazelike stone fortress, it’s no refuge from the wolves and the freezing wind. It’s more like a trap. What they discover can stop the heart—or worse. As terror takes a new shape, the real battle for survival begins in this unrelenting six-part serial from Academy Award–winning filmmaker and writer Guillermo del Toro.

FALLING DOWN

A group of mercenaries on an unsanctioned mission survives a plane crash in whiteout conditions in the Tian Shan mountains. The men are accustomed to danger. Now they’re growing accustomed to fear.

Team leader Liev and his band of survivors are stranded in the bitter winds with little hope of rescue—or outlasting the wolves that have scented blood. In the distance is the apparent sanctuary of an abandoned stone fortress. That an ancient bulwark even exists on this forsaken summit is beyond comprehension. So is what lies on the other side of its walls.

THE PIT AND THE BOX

On an isolated mountain, a stone labyrinth provides rough shelter for a band of mercenaries. At its core lies a centuries-old mystery. But in part two of The Boy in the Iron Box, no secret is safe.

A concealed pit; an iron box, wrapped in chains; a statue of a boy. What unknowns await the anxious, disoriented team in this strange ruin? Night will tell.

THE HUNTED

Their radio is sabotaged. The wolves are gathering outside. And for the increasingly desperate mercenaries, the worst is yet to come in part three of The Boy in the Iron Box: the box is empty.

In the wake of an inexplicable disappearance, Liev and his men use their tactical skills to last the night—by going hunting. Following a small, bare footprint in the snow leads only to the realization that someone, or something, is hunting them.

RISEN

What has been awakened is unbound. The Boy is getting his first taste of freedom. As their comrades fall, fear threatens to consume the survivors in part four of The Boy in the Iron Box.

Liev’s plan: get his men out of this ancient stone prison, take their chances with the wolves, and descend the summit at first light. But in this snowbound hell, there’s soon to be a frightening new twist to survival.

SIEGE

The mercenaries set an explosive scheme in motion to blow this bad dream to smithereens. But in part five of The Boy in the Iron Box, they soon find that even the best-laid plans can backfire.

With the morale of the team fraying, Liev makes a vow. He’s not going to leave anyone behind until the last stand is seen through to its cold and bitter end. On this night, it’s Liev who lies in wait to face everything he’s feared. It’s nothing like he expected.

ENCOUNTER

Dawn breaks, but the nightmare only intensifies in the shocking finale of The Boy in the Iron Box. In a final confrontation, the true nature of the Boy is coming to light.

In a stone chamber, the familiar young figure lingers with an unsettling calm. He has a question for Liev: Do you want to stop me? Now, for two merchants of death, each with his own purpose, one last contest lies ahead.
