Nico is initially introduced as moving to a new school, where the rest of the main characters, his classmates, are introduced. In the first episode, he states that he progressively lost his sight, and was therefore integrated into a school for visually impaired people for the last few years. This is later retconned to him being blind from birth: This was expressed explicitly in one episode, he tells a supermodel that has recently lost her sight that it is best to have been able to see once, than to never have seen like him. Other characters include:
Patty, Nico's neighbor, classmate, and best friend. She always ties her blonde hair in a pony tail.
Oscar, a classmate that perpetually chews bubble gum, who always tried to trick Nico or Tom into tripping or getting into trouble. He feels that Nico is stealing his popularity.
Flappy, Oscar's dim-witted and good-hearted, yet only, henchman. He is a bit egocentrical, believes he has psychokinetic powers, and has a short stature.
Aisha, Nico's classmate of African descent who perpetually is trying to invent something. Seems to be allergic to Flappy.
Tábata, Nico's baby sister
Boris, Nico's family's ever-hungry pet chameleon, who more than changing color, changes his shape. Always seen chasing a bug.
Charlie, Nico's classmate of Japanese descent. He loves small creatures in general and carries a different insect or rodent around in his pocket in each episode hoping to care for it, much to the dislike of the creature in question. The creature always ends up escaping near the end of the episode, usually after interacting with Boris or Tom.
Caifás, Nico's elderly, ill-humored, and very rich neighbor. He hates children in general, but he hates blind ones even more so. On one occasion, for example, he built a robotic bat for the sole purpose of bothering Nico.
The episodes usually showed a modern city, but frequently featured improbable plots. Usually, there was a background story involving the animal characters Tom and/or Boris. Many episodes happening in a believable scenario featured a reduction in visibility where Nico would save the day by quickly telling people how to "see" without using their eyes, enabling them to, in the above case, escape the building before the fire spread.
Closure
Each episode closed with a "Watch Out!" segment narrated by Tom. It consisted of stating a little-known fact of what blind people can now do. Each segment typically started out with something along the lines of "You think someone that is visually impaired can't go skiing?" and then proceeded to explain, in the given example, that blind people can ski if a guide skis in front of them with a speaker on his/her backpack to shout warnings at the skier, and the blind person following the sound of his/her guide's skis sliding on the snow. The example would then be followed by some sort of more or less comical note, to which Tom winked at the audience. Often, these "Watch Out!" notes were a show of a much later episode. Immediately afterwards, Nico's voice would give an advance of what the next episode would be about, while brief images of that episode appeared on screen. During the credits, a comical sequence where Boris chased a dragonfly was shown.
