Anna is a single mother who is barely capable of keeping up with her young, strong-willed daughter, Alice, who seems to take more after Anna's independent and seemingly-perfect older sister, Shirley.

It's all a little more than she can bear. Suffice it to say, the LAST thing she needs is to come down with the shrinking disease, and be stuck at the size of an ant, at the mercy of her sister, daughter, and daughter's friends. 

A schoolbus shrinks and winds up being taken home by an unaware little girl, but how long will it remain unnoticed, and what will Mandy do if she finally discovers her microscopic friends?

Samantha is your average young girl. So is Mary. But when Mary shrinks due to an unpredictable disease her friendship with Samantha is reduced to nothing. When you remove equality from the relationship, all that's left is a couple of calories.
