Buster joins Carlos and Mora on a road trip through the Sonora Desert. En route, they load up on snacks at a Latin American grocery store, meet Ariana who plays in a local Mariachi band, and cope with flat tires and car break downs with help from expert desert dwellers.

While traveling in Miami, Buster misses his Mom. He decides to give her a call and is disappointed when she rushes him off the phone at first. Later, they make up and Buster decides to help her with a food column she has to do for the newspaper. He researches both Cuban and Greek food and becomes an amateur reporter. Along the way, he meets a new friend and learns about bilingual schools and other interesting topics.
