Former Marine Louanne Johnson lands a gig teaching in a pilot program for bright but underachieving teens at a notorious inner-city high school. After having a terrible first day, she decides she must throw decorum to the wind. When Johnson returns to the classroom, she does so armed with a no-nonsense attitude informed by her military training and a fearless determination to better the lives of her students -- no matter what the cost.

Chantel Mitchell, a hip, articulate, black high-school girl in Brooklyn, is determined not to become "just another girl on the IRT" (the IRT is one of NYC's subway lines). She dreams of medical school, a family, and an escape from the generational poverty and street-corner life her friends seem to have accepted as their lot. But personal and sexual challenges confront Chantel on her way to fulfilling these dreams.
