In a world where voices can traverse space and time, you, a down-on-your-luck paranormal investigator, are contacted by a series of ghostly apparitions seeking closure. Each voice tells a fragment of a story, causing you to piece together their unfinished business. As you interact with these restless souls through a mysterious phone app, you soon uncover dark secrets about each ghost's life—and death. Your decisions will determine not only their fates but also your own, as the line between the living and the dead blurs. Will you help them find peace, or will you become one of their hollow echoes?
