The film, directed by Jennifer Grausman and Mark Becker, follows Stephenson's class a semester after her students have won more than $750,000 in scholarships -- at a school where 40 percent of students don't make it to their senior year. Consistently successful in getting her graduates out of the inner city and into such culinary cooking colleges as the Art Institute of Atlanta, the Culinary Institute of America and Monroe College in New Rochelle, N.Y., she is no-nonsense, all business. Her manner may be brusque, but her students are responsive.
