SYNOPSIS:

One year after the death of their mother, SARAH, her widower ELIAS (30s) is a hollow shell of a man. Consumed by grief, he is selling the family home and has shut out his twelve-year-old twins, LEO and LILA. On their last family trip together, the trio built a snowman named FROST in the shadow of the mythical Never-Melt Summit, using Leo’s whittling knife to carve his smile and wrapping him in Lila’s oversized red scarf. Before walking away, Elias made a vow: if Frost survived the year, they would return to build him a brother. Now, with a brutal winter storm approaching, Elias breaks that promise, telling the kids he doesn’t have the energy for "ghosts."

Refusing to let their mother’s memory disappear, Lila and Leo sneak out before dawn and hike up the treacherous, avalanche-prone mountain. Above them, the ancient magic of the Never-Melt aurora strikes the summit, sending a violent shockwave of energy racing down the slopes. It hits the forgotten, decaying snowman in the clearing below. Awakened by the magic and the memories tethered to the red scarf, Frost comes to life. But a violent gust of wind rips the scarf away, causing his memories to vanish. Desperate, Frost tumbles down the mountain, retrieves the scarf, and begins tracking the twins.

As the children navigate brutal whiteout conditions, Frost follows in the shadows. He longs to reveal himself but is terrified of his own monstrous, decaying appearance. Instead, he leaves behind a carved, lopsided smile on a frozen sapling—a beacon of warmth that proves to Lila he is real. When Leo slips on black ice and dangles over a massive abyss, a collapsing ice slab threatens to crush him. Frost sacrifices himself, wedging his snowy body into the gap to hold back the crushing weight. He saves Leo, but the effort melts away his right arm and leaves his glowing blue core flickering on the verge of death.

Back in the village, Elias discovers the twins are gone. Terrified, he sprints up the mountain. Along the way, he discovers a massive, flash-frozen handprint in the rock. Pressing his hand into it, Elias feels the exact, impossible warmth of his late wife’s hands. Something in him fractures. He presses his forehead to the stone and, for the first time in a year, weeps. Realizing the magic is real, Elias pushes forward with fierce determination. He reaches the twins in an ice hollow just as Frost collapses entirely, reduced to nothing but his fading blue core and the tattered red scarf.

With the storm raging, Elias leads the children up a sheer, two-hundred-foot vertical ice wall to reach the Never-Melt summit. Halfway up, the core begins to die from the freezing wind. In a desperate move, Lila presses the freezing magical core against her own bare skin, using her body heat to keep it alive. Leo wraps himself around her to shield her from the wind.

At the peak, Elias and the children use the sacred Never-Melt snow and Leo's knife to rebuild Frost's body around his core. For a terrifying moment, the snowman remains lifeless. But as Elias apologizes for giving up, the mountain answers. Frost’s core erupts with blinding aurora light. The magic arcs into a second mound of snow the children built, bringing PINE—the promised brother—to life. The red scarf magically stretches to bind the two snowmen together. As Frost reaches out to gently touch Lila’s face, she feels the unmistakable, comforting warmth of her mother’s hand. The family finally heals, walking down the mountain together. One year later, they return to the summit — and Frost and Pine are waiting.
