Tan frágil como un segundo.

Julieta is 17 years old and lives with her mother and her siblings in a small town. Her boyfriend, Gabriel, gets her work with various clients, from truck drivers to government officials. Sofía is a 16-year-old student at a private high school in the capital city. With her best friend, they enter the advertising world and receive a tempting offer. Like threads in a web, Julieta and Sofía converge in a world where everything can be bought and everything can be sold, where certainty is as frail as a second.
