Twelve year old Cassi Whelan and her dad have just moved into a repaired house on the edge of Christchurchs Red Zone. Although Cassi was only four when earthquakes decimated Christchurch, her memories still haunt her. An obsessive runner, she finds the wide open spaces of the cleared Red Zone suit her perfectly. However, she becomes suspicious about strange comings and goings at the broken down house next door. A chance meeting with a boy who lives on the other side of the house who is a tech geek leads to them setting up a surveillance system to investigate what is happening: and the adventure begins.
