After his father's accidental death, teenager Kale becomes withdrawn and troubled. When he lashes out at a well-intentioned, but insensitive teacher, he finds himself under court-ordered house arrest. His mother tries to cope, agreeing to extra shifts to support herself and her son while trying in vain to understand the changes in his personality. The walls of his house begin to close in on Kale, but he attempts to extend the emotional and physical boundaries of his confinement. His interest and gaze turns toward his neighbors, including a mutual attraction to the new girl next door. Together, they begin to suspect another member of their community, a quiet single man, is a serial murderer. Are their suspicions simply the overheated product of Kale's cabin fever and vivid imagination? Or have they truly discovered a brutal criminal on a destructive spree, and could this knowledge cost them their lives?
