4 school friends and their singing teacher form a fun and very promising romantic music cover band until a fierce fight separates them. 7 years later and thanks to the marriage of one of them, they meet again. When the bride is stood up at the altar, the problems they all have come to light: Daniela, the bride, wants to leave her father's house and find a man with whom she can be happy; Rocío is about to be fired from the school where she has been working as a singing teacher for more than 30 years; Ana is about to bankrupt her driving academy and separate from her son's father because she feels he has no ambitions; Paloma, a psychologist who has never practiced because she never took care of her husband's children, discovers she is pregnant two days before her husband is arrested for a corruption case; and Karla, the successful show business anchorwoman of the newscast does not know how to handle the tortuous romance she has with the husband of one of her co-workers. An impromptu and emotional bar presentation opens up the possibility for these 5 women to get back together as the cover band they had when they were girls, but first they will have to resolve their complicated and chaotic lives and the marked differences that led them to separate.
After that and only after that "Las Fans" will be ready to enjoy life, to enjoy their friendship and to go out to devour the world with devour the world to the sound of iron music and ¡A grito herido!
