Kevin's neighbor and childhood playmate, Cata, is starting the same school as Kevin and Fede. But she is sporting a new, more mature style and insists that she be addressed by her full name, Catalina.

Unlike Kevin and Fede's previous school, this one is co-ed, arousing some anxiety in them. Fede even confesses about a nightmare in which he arrives at school naked.

Los Años Maravillos incorporates genuine archival news footage, giving us a sense of what it was like to live in Colombia in the mid 1980s. In this segment, we see reports regarding the civil conflict involving rebel forces used as a backdrop to the family drama unfolding at the González dinner table.

It's the summer of 1985 and 12-year-old Kevin González is spending his time playing banquitas, a Colombian form of street soccer. His older brother, Leo, is forever tormenting him, while his best friend, Fede, does his best to intervene.

"Toda la vida" ("All My Life") is the theme song which opens the Colombian version of the American hit series The Wonder Years. The song is a cover of a hit Italian song,"Tutta La Vita", written by celebrated composer Lucio Dalla. Sung by Mexican singer Emmanuel, this version was number one on the Latin charts for three weeks in 1984, replacing a different version of the very same song sung by Cuban singer Franco.
