Asteria Band is a campus band with six members who appear to be close-knit. But behind that harmony, Raka and Tania—two vocalists and a couple—are secretly battling their egos. Raka's increasingly dominant influence slowly pushes Tania aside, causing tension in rehearsals and beginning to fracture the band's atmosphere. Nadya, the keyboardist, witnesses the cracks in their relationship slowly spreading to the rest of the band. Their moments together turn into distance and discomfort. When Tania decides to leave the band after the festival, Asteria is faced with a harsh reality: that night might be their last performance together. Without large stage scenes, Nada yang Retak takes the audience into the small spaces behind the band: the studio, the staircase, and simple, emotionally charged conversations. This film highlights how love and ambition can strengthen each other, but also destroy each other.
