Arlya, a small town in Southern Ontario, is rocked by a gruesome crime. Four friends must work together with Detective Dylan Grey to find a pattern, a bike, a clue, and a sister before it is repeated.

James and his three best friends, Owen, Tommy, and Mike, have just finished school for the summer. The plan is the same as every other year: they are going to build the biggest fort yet, deep in the Dhoon Woods. After stumbling across a tiny, seemingly unimportant wooden hut, a series of crimes take place and their plans change.

Arlya falls into itself. Doors are locked, curtains drawn, bikes are put away, strangers invade, and kids are off the street. In the first week of summer vacation, a dark and disturbing family history is uncovered; friends turn on each other; a storm rolls through town; and a monster is hiding just out of sight, smiling its toothy grin and crawling through the corn.
