Thirteen (1997)

This film follows a year in the life of a young African-American girl as she turns 13. Temporarily running away from home to sort out her life, which of course sends her family and friends into a frenzy, she soon returns with new purpose - to buy a car. This sends her into a working frenzy - baby sitting, mowing lawns, washing cars, and pursuing jobs obviously advertised for adults. The film ends with Nina's 14th birthday and promise of her future.
