Jake Hayes is missing. This much is certain. At first, his wife, Nina, thinks he is blowing off steam at a friend’s house after their heated fight the night before. But then a day goes by. Two days. Five. And Jake is still nowhere to be found.
 
Lily Scott, Nina’s friend and coworker, thinks she may have been the last to see Jake before he went missing. After Lily confesses everything to her husband, Christian, the two decide that nobody can find out what happened leading up to Jake’s disappearance, especially not Nina. But Nina is out there looking for her husband, and she won’t stop until the truth is discovered.
