The story is about life of a Latino community in Echo Park, Los Angeles. Latino girls celebrate reaching womanhood at the age of 15 years old which gives the title of the film.
Pretty realistic look at how each of the characters spend their free time! Watched my first Mexican film a few years ago and I am still quite amazed at how some of the accent reminds me of "Speedy Gonzalez" which is a cartoon character. The grandfather has exactly such an accent! The two neighbors remind me of Keanu Reeves and Richard Gere!
