Julia (Rojo) is a phone operator in Mexico City who divides her time between her job, her daughter and the danzon: a cuban dance very popular in Mexico and Central America. Every wednesday Julia does the danzon with Carmelo (Rergis) in the old "Salon Colonia". They've danced for years but barely know each other. One night Carmelo disappears without a trace. Feeling lonely and sad, Julia takes a train to Veracruz, where she knows Carmelo has a brother. That sudden trip will change Julia's life forever.—Maximiliano Maza <[email protected]>
