Edward Stanton is a 39-year-old with Asperger's syndrome and obsessive-compulsive disorder who tracks his most common waking time (7:38 a.m.), refuses to start his therapy sessions even one minute before the appointed hour (10:00 a.m.), and watches exactly one episode of Dragnet each night (10:00 p.m.). When 9-year-old Kyle and his mother move in across the street, Edward's timetable is upended, and for an exhilarating 600 hours, he opens his door to new neighbors and new problems. The solace of friendship, however, comes with risks ? heartache, uncertainty, and change. Ultimately, Edward must decide whether to remain in his rigid, solitary world or embrace the beautiful vagaries of the heart.
