Grandparent Trap: The Family Game

The Blaine children don't have grandparents of their own, so with their mother's help they invent a game where they spend a week of summer vacation with a carefully chosen-yet unwitting-set of grandparents. This is now their third year of playing The Family Game. Unlike the other times, this new couple, Janet and Warren Chapman, grow quite attached to the Blaine children.When the week is up the children mysteriously disappear (when they return home), leaving Janet and Warren heartbroken. Warren begins piecing together clues and tracks down Laura Blaine and her children, requesting they remain a part of their lives. As "not revisiting the grandparents" is one of the rules of The Family Game, Laura adamantly refuses, until a family secret is revealed and changes everything.
