Identical twins Cassie and Caitlyn Waters have adjusted to small-town life, but they're still not used to seeing visions of the future. When a troubling and mysterious package arrives with a connection to the father they've never known and the grandmother they never knew they had, the twins distract themselves by planning a birthday bash with their new friends. But when the visions of the upcoming party show it will be more of a catastrophe than a celebration, the girls have to work together to keep it fiasco-free.
