5Sixty-one-year-old Meredith Taylor answers her door to find a worried-looking little girl, who announces, "I've come to stay with you for a while...I'm your granddaughter." From this unexpected and jaw-dropping event, Meredith and her husband Andy are thrown into an emotional storm.

Somehow though, in the midst of the rising pressure and the dizzying complications, six-year-old Sam manages to win Meredith and Andy's hearts, even as they watch their own beloved son falling apart emotionally.
