Trini (María Castro) is a big band singer who, in recent years, has traveled all over Spain. But an unexpected event forces her to drop her passion and return to La Gloria, the neighborhood she grew up in and where all her family lives. Here, she is reunited with the people from her past, her friends and the man who was once the love of her life. Trini’s ex is the owner of “La Bamba”, a karaoke bar that has seen better days, but is starting to shine once again. “La Bamba” gradually becomes a meeting point for locals, a place where they can vent their frustrations and rejoice in their existence, and all to the backdrop of music, a lot of music.
