Jamie Oliver brings his Food Revolution to Los Angeles in the Season 2 opener, and things get off to a rough start when the Los Angeles Unified School District (LAUSD) refuses him access to their schools.

MLA CEO Mike McGalliard delivers a shattering blow to Jamie and his 10 teenaged culinary students at West Adams Preparatory High School: They've been banned from serving food on campus. Heartbroken and defeated, Jamie makes an emotional plea to the kids' parents and gives the students a graphic reality check about what is really in the foods they're eating every day.

Jamie dresses as a tomato and distributes free healthy lunches outside a Los Angeles public school, hoping to garner parental support and gain access to the schools. Later, he meets a 17-year-old who fears she'll inherit her parents' diabetes.

Using a simple math equation, Jamie teaches the West Adams High students a practical lesson about the short term consequences of their unhealthy food choices. The message becomes far more emotional when Jamie invites a few guests suffering from the painful, long term effects of diabetes, heart disease and high blood pressure to share with students some unforgettable stories of their struggles. Meanwhile, Jamie helps a busy, devoted single father and his two young boys to open their eyes to their destructive daily cycle of eating fast food, and to rediscover the physical and emotional value of preparing and eating a home cooked meal together. Things really get ugly when Jamie learns first hand who was responsible for the decision to revoke his film permits and ban him from preparing food in any school across Los Angeles. He refuses to accept defeat and devises a plan to move his kitchen across the street from West Adams High, but will this be enough to make a real impact?

A meeting with the district's incoming superintendent gives Jamie hope; Jamie puts together a cooking competition for students.

Jamie gets a break when he's given the chance to work with another school district, but before long, he's faced with another big obstacle. Also: Jamie Lee Curtis presents him with an award from the UCLA School of Public Health; and later, he tours an organic school garden in Santa Barbara, Cal.
