Popular cheerleader Nina Deer's (Elisha Cuthbert) seemingly unblemished suburban world is turned upside down when her parents (Edie Falco and Martin Donovan) adopt their recently orphaned goddaughter Dot (Camilla Belle). Dot's arrival delivers a blow to Nina's idyllic social life and triggers the unraveling of the family's darkest secrets.

Both Nina's family and friends, including the school hunk Connor (Shawn Ashmore, The X-MEN trilogy), develop an odd fascination with Dot and confide in her their troubling secrets. Dot quietly shoulders the burdens and secrets of those around her, while continuing to hold what is perhaps the biggest secret -- her own.
