By now life seems settled and done. Reduced to a caregiver of the old and moribund, plagued by a drug-addicted daughter who can't stop. There's no future. But one day, by chance, she finds a false wall in her bedroom, a wall that hides two corpses. That's what happened to her partner, who had oppressed her for years with abuse before disappearing. That's what happened to her son, who she believed ran away from home. They have always been there, with her. Someone killed them. She cannot call the police. She'd be the prime suspect. The only suspect. She can't do anything but hide the bodies. She'd like to forget, but cannot. Because in this building there are other faux walls and other hidden corpses, and several people have disappeared suddenly. She just has to try to find the truth.
