A Letter Across the Underworld

In the dead of night, every paper effigy in an abandoned funeral-paper shop quietly turns to face the back room. On the first night college student Lin Yan is forced to take over the family business, he receives a call from an unknown number: “Don’t turn around. Something behind you is watching.” A drop of blood on the forehead of a paper child, and a whispered “Thank you, big brother,” set him on a path with no turning back. A homeless man frozen to death buys clothes to honor his mad mother; an unnamed water ghost clings to the words, “I couldn’t hold on to him.” Behind every eerie tale lies a human longing that has yet to fade. Using paper as his medium, Lin Yan brings figures to life with his brush and guides the dead to rest. Yet the blue thread left behind by the “ghost who bought clothes” and the icy handprint that lingers from the “water ghost’s debt” quietly drag him into an even deeper whirlpool. A mysterious black letter arrives, offering a million in payment and pointing to the calamity of “ghost soldiers marching through the streets.” The ink on the letter comes from the same source as the notes his grandfather tore up before disappearing. A figure in a black raincoat follows him through the night rain. A cold-faced undertaker offers to work with him, while a rival geomancer has already laid a deadly trap. An ancient village known for its Nuo opera conceals a bloodline secret, and a fragmentary manuscript reveals the true duty of a “guide of the dead”: it is not a profession, but the role of a gatekeeper who walks between the worlds of yin and yang, keeping restless obsessions in balance. As urban legends erupt one after another and the divide between yin and yang threatens to collapse, Lin Yan realizes that his grandfather’s disappearance, the strange black letter, and the black threads entangling all things all point to the same truth, buried for a century. With his brush, he guides the dead onward. But what he must deliver is not only their lingering obsessions: it is also a catastrophe sweeping over the living world, and the fate he cannot escape. See the ghosts, and see the human heart.
