One year following their deaths in a late-night car accident, teenagers Danielle, Marco, and Christopher return, in spirit, to the sleepy New England suburb of Avon. Over the course of the evening, the three will drift into and out of the lives of those who knew and were affected by them. None is more affected than Tim, survivor of the crash, who plots a grisly act of remembrance, and Brooks, the well-intentioned police officer who first discovered the crash and whose life has changed in startling ways since.
