Ramón, a trim and handsome music student in his twenties, takes classes at the local conservatory in Guadalajara.

He lives in a rundown overcrowded boarding house, where he practices on his French horn and gets together with his boyfriend Rodolfo, a thirty-something neurosurgeon with a successful career in pediatric medicine.

Their secret encounters always seem to be interrupted by visitors and phone calls by Rodolfo's meddlesome widower mother, Doña Herlinda.

Doña Herlinda pretends that she knows nothing of the true nature of the relationship between her son and Ramón who she really dotes on like a second child.

His severe mother is startled finding his son living in close quarters with Rodolfo, but Doña Herlinda not only welcomes the couple warmly but smoothed things out with them so Ramón's parents depart assured that their son is well-taking care of in spite of his a typical living situation.

Rodolfo gets married and leaves with Olga to their honeymoon in Hawaii while heartbroken Ramon remains behind keeping company to Doña Herlinda who tries to cheer him up and helps him drying his tears.

For her part, Olga, an educated and independent woman, wants to continue working and, have a life of her own, far from the traditional role assigned to a Mexican housewife.
