Cory Vickers lives with his sisters Katie, Gabby, and Maddie in the house that used to belong to their mother before she moved away. One day, they find and activate mom's old shrink ray, shrinking Cory and maybe some of his sisters. Whoever is shrunk is stuck at their new tiny size until the shrink ray can unshrink them. But who knows how long that will be? And how will the shrunken sibling(s) navigate and survive in a giant world? They will need help from their giant sister(s), that's for sure!
