Twins Crystal and Amber have the same goal: to be the first in their family to graduate high school and make something of their lives. When one gets pregnant during their junior year, they promise to raise the baby together. It's not easy, but between their after-school jobs, they're scraping by. Crystal's grades catch the attention of the new guidance counselor, who tells her about a college that offers a degree in automotive restoration, perfect for the car buff she is. When she secretly applies—and gets in—new opportunities threaten their once-certain plans, and Crystal must make a choice: follow her dreams or stay behind and honor the promise she made to her sister.
