But whether she did or not, the kids have a job to do -- Babs Magee is up to her old tricks and plans to take credit for sewing the flag. Abigail and the boys see this as their chance not only to stop Babs, but also to set history straight.

But once they start trying to figure out the truth, what they discover surprises them all....
