After twenty years of haunting silence, Julian, a restorer of water-damaged photos, is pulled into a supernatural deluge where the rain carries the consciousness of the drowned. To stop the "Great Exposure"—a chemical and atmospheric event threatening to overwrite reality with the ghosts of the past—Julian must confront the memory of a lost childhood friend and use his knowledge of photography to fix a tragedy that was never meant to be preserved. By choosing to let go rather than hold on, he breaks a generational cycle of grief and finally finds clarity in the dry light of the present.
