Only I Hear: the Echoes on 67th

Gwen works as a night guard, and she can hear the echoes of tragedies that happened in the building she protects. When she hears the screams of a maid named Lila, she is certain Lila has not stolen anything, even though everyone else believes the accusation. Gwen refuses to bow to the corrupt bosses above her and begins chasing clues, including erased security footage, a concealed floor, and a hidden room. Her search uncovers a murder from five years ago that is linked to Lila's family.
