Laura and Owen buy a secluded cottage within the edge of the Maximum District. Aged mines riddle the hills surrounding their brand-new home and soon after moving in, Laura starts to listen to faint snatches of birdsong. Her spouse, wrapped up in his brand-new job, is seldom around. Anxious and only, Laura worries she’s developing tinnitus. Her doctor will get nothing wrong. After that an archaeological dig on the neighbouring hill unearths some disturbing finds… and Laura’s lifestyle starts to be terrifying.
