This is the story of two mothers, strangers to one another.
The first has two children -- twins, a boy and girl, who are seniors in high school. She wants their last Christmas as a family living in the same home to be perfect, but her husband is delayed returning from a business trip abroad. And then there's an accident -- a fatal one involving a drunk driver.
Meanwhile, the other mother has a daughter who needs a new heart, and so the loss of one woman becomes the miracle the other has desperately prayed for. While one mother grieves, and pulls away from her family, the other finds that even miracles aren't always easy to receive.
