Fofó's friends wait for him to explain this interesting mystery. They have been friends since nursery. Loli is a brilliant student. Fofó is funny and moody. Fran loves sport. Eli is sensible and Tebi always talks too much. Gugui, their Moroccan friend, is honest and loyal. Bea likes art. Baldo goes unnoticed. Chulo is nervy, Danae is a pretty girl... They are all different and similar at the same time.
