Lucy Neville, who has just graduated from university, faces a difficult choice: find a job or go to Latin America, the exotic land of her childhood dreams. She arrives in Mexico City with almost no money and only a basic level of Spanish and quickly finds a job teaching English. Thus begins a comic tsunami of adventures, during which Lucy, crossing the multi-layered space of Mexico City, meets a variety of people - from street vendors to crazy gringos, from scientists to socialites.
