Cousins Lucas and Emma love to spend time in their grandparents' garden. One day, with the help of Grandpa and Nona (their grandmother), Lucas helps plant various vegetable seeds while learning about the uniqueness of each one. To his dismay, the plants aren't ready by dinnertime, but he and Emma find plenty of fresh, scrumptious vegetables at the store. On another day, the two ride their bikes to Nona's house again, but this time their friends Dylan and Zoe tag along, and the garden as a whole turns out to be as much a source of fun as it is vegetables. The four of them dig up treasures, discover bugs, and get into a jovial conversation about who would be which vegetable and why. After much laughter, Nona calls the kids in to make homemade pizzas and they eventually enjoy a delicious and healthy dinner together.
