The world is reduced to a black and white silent film, and the sound is frozen into ice. Elio, an illegal sound alchemist, is trapped in a lengthy pseudo-immortality due to a distortion of his perception of time. What he longs for is not immortality, but to regain the normal flow of time, die as a mortal, and reunite with his lover who died young. When he unexpectedly heard his lover's cry for help from before the disaster in an ancient mirror, and discovered that there were still afterimages of color and sound in the mirror, his path to personal salvation suddenly intertwined with the survival of the world. A Silent Order that attempts to freeze time, the truth of a covered up disaster, and the secret of his lover trapped in the middle of time force him to risk everything. The last sound he wants to refine will determine whether time returns to eternal silence or regains flowing life.
