Sound recordist Ivy Marsh was hired to capture silence. Instead, the silence started talking. She has 21 days to record all 112 rooms of Kestrel house before it's blown off it's mountain. Then her recording whisper her childhood nickname, and the the names of people who are about to die. Only Jude, the demolition man she's falling for believes her. Twenty years ago, Ivy's mother was declared dead inside those walls. Now something in the house is counting down. Some silences are waiting to be heard.
