At midnight on Halloween in a New England suburb, a car carrying five teenagers veers from a winding road and slams into a tree, killing three of them. There are two survivors, one suffering brain damage. Only Tim is left alive and unharmed, but his life has been irrevocably torn apart. A year later to the day, summoned by the memories of those closest to them, the three who died have come back on a chilling final mission to revisit their families, friends and those they hold responsible.
