In a snowy, pine-scented forest, a group of workers with power tools cut down trees, burn some, and package others into trucks. The assembled trees are sent to facilities and sold as Christmas trees, but these trees are not just wooden decorations—they are sentient beings who feel every cut, burn, and shove. They try to communicate in their own language, reaching out with what tiny signals they can muster, but the humans hear nothing and understand even less.
The story follows a family of four among the harvest: Jim Macmichael, Jonathan Torrens; Cadence Macmichael, Sarah Dunsworth; Krista Macmichael, Maris Morgan; and Jason Macmichael, Jayden Taylor. Their lives intersect with other humans in perilous ways: a man with the disturbing fixation of wanting a sexual encounter with a tree, a girl and her mother caught in the orbit of the trees’ growing fury, and a woman who finds herself pressured by a boyfriend as danger closes in. Amid the chaos, a man who appears in a tree suit—voiced by Jason Johnson—moves through the growing nightmare, his presence a bizarre and unsettling facet of the invasion.
On Christmas Eve, the trees observe the humans’ celebrations with a sense of distant sorrow, apparently unable to hear the pleas of their captors. The world continues its holiday cheer, oblivious to the horror unfolding in the woods, where the trees’ suffering ends in silent, collective rage.
Christmas Day erupts into unthinkable violence. Cadence Macmichael—the young girl in the family—falls victim to a brutal attack by a tree, and a frightening moment occurs when a Christmas star is driven into her father’s throat as her mother and brother cry out in horror. Elsewhere, a mother and daughter discover that their tree has decapitated their cat, and they are chased by the encroaching forest. A woman and her boyfriend face a harrowing fate as the tree’s branches rend their eyes from their sockets, while the man’s leg is severed with an axe. The carnage multiplies across the world as trees strike indiscriminately, and a mother and her baby are separated in the mayhem; a tree leaps onto the baby’s head, crushing it, while others drag the bodies behind them in a grim rolling march of vengeance.
The trees’ assault spreads relentlessly, leaving a wake of crushed lives and severed fates in their wake. The human world tries to cope with the impossibility of communication with their silent aggressors, while the forest becomes a battlefield where nature asserts its unhearing, unstoppable authority. In the end, the trees’ onslaught continues, dragging the remains of what humans once called Christmas into a stark, brutal new reality.
