Nahla's science project turns out to be the start of a group garden on her school's rooftop. During their lunch hour, students put on their gardening gloves to plant, weed, and water. Thanks to the school, yummy veggies are turning up everywhere, including the school cafeteria and the Helping Hands Kitchen. But it seems like not everyone is happy. Somebody is trying to ruin the success of the Get Fresh Tomato Fest, the rooftop garden party. Is it her classmate who calls himself "the potato chip king" and makes faces when he sees all the new healthy choices at the lunch counter? Is it the girl who loves playing tricks? Or maybe it's the maintenance crew, who complained to the principal about dirt being tracked through the school. Nahla is determined to save the day and the garden.
