Allison Scott is 15 years old, only child and has the richest parents in the whole city. She has the perfect hair, wears the perfect clothes, has the perfect friends and leads the perfect life.
Hannah Adams is also 15 years old and is less lucky. She lives in an apartment with her two younger brothers and mother and she has no idea who or where her dad is.
Although these two girls live in the same city and go to the same school, they have never met each other. Due to this simple fact, they also have never noticed that they look exactly alike.
