Dana Catrell was the last person to see Celia alive-- but suffering from mania, the result of her bipolar disorder, she has troubling holes in her memory... including what happened on the afternoon of Celia's death. Her husband's odd behavior and a detective's probing create further complications, and the closer she comes to piecing together the shards of her broken memory, the more Dana falls apart. Is there a murderer lurking inside her... or is there one out there in the shadows of reality, waiting to strike again?
