The adventures of a group of secondary school . Juan, one of the group, falls in love with Sara, the new girl.

A lovers' break-up, a mysterious website called www.kellerteve.net, a disturbing phone call summoning the main characters to a midnight rendezvous in an abandoned zoo, and the theft of a motorbike leading to a dangerous chase in the subway are only the start of this unnerving story.

Plauto, the clown, tells us the story of the Circo de las Alegrías. Doña Alegría, owner of the Circus is determined that her son Palevhi, maintain the classic line of the show, which begs for a complete renovation.

One night in September, Palevhi decides to inform the big family of the circus the final closure. Tears of frustration give way to the search for solutions.
