In 1961, a young Abraham Quintanilla and his band "The Dinos" face rejection from a white restaurant owner, who turns them away for an audition based on their "Whites Only" policy. Shortly after, they perform at a nightclub named "Lerma's" for a Mexican audience. However, chaos ensues when they choose to sing "We Belong Together", straying from music typically embraced by their cultural background, resulting in a riot that forces the band to escape.
Fast forward to 1981, and Abraham is now married to Marcela Samora and has three children: Abraham III (known as A.B.), Suzette, and the talented Selena (played by Jennifer Lopez). Recognizing Selena's singing prowess, Abraham establishes a new band called Selena y Los Dinos, featuring Selena as the lead vocalist, A.B. on bass, and Suzette on drums, despite their initial hesitations. In tandem with his aspirations, Abraham also launches a restaurant called "Papa Gayo's", urging Selena to learn Spanish to connect better with Mexican audiences—a struggle he faced in his youth.
Tragically, the economy takes a downturn and the Quintanilla family's restaurant goes bankrupt, prompting them to relocate to Corpus Christi, Texas, where they seek refuge with Abraham's brother. In this new environment, Selena attempts to shine at a local carnival, but her performance is met with indifference. However, her fortunes begin to change when, while at the beach, Marcela hears a catchy song on the radio and teaches Selena a dance known as "The Washing Machine," which catapults her and her band into greater popularity.
By 1990, Selena meets guitarist Chris Perez (portrayed by Jon Seda), who becomes a vital member of the band and forms a close bond with her. Abraham, however, is not pleased with Chris due to his tumultuous past involving hotel damage with his previous rock band; despite Chris’s instrumental role in the band's success, Abraham decides to fire him when he catches Selena and Chris sharing an embrace before a concert. He warns a distressed Selena that following Chris would lead to the band's dissolution.
Despite the obstacles, Selena and Chris pursue a secret romance, and when Selena expresses her desire to marry him immediately, they elope in 1992, much to the surprise of the media. This decision surprisingly earns the approval of Abraham, who ultimately just wants what’s best for his daughter. Chris is welcomed into the Quintanilla family, reclaiming his position as the guitarist for Los Dinos not long after.
During one of Selena's electrifying performances, Jose Behar, head of EMI Latin, approaches Abraham with the exciting news of a proposed English-language album for Selena. By 1994, she launches her first boutique named Selena Etc., with her fan club president, Yolanda Saldivar, managing the store. Selena's album Selena Live! garners a Grammy Award for Best Mexican-American album, validating her burgeoning career.
As 1995 begins, Selena embarks on her much-anticipated Crossover Album. It’s then that Yolanda gifts Selena a friendship ring, deceitfully stating that it’s just from her. However, the situation turns dire as Selena discovers from Abraham that Yolanda has been pilfering from the fan club, leading to major financial discrepancies. During an intense confrontation at Q-Productions, Selena along with Abraham and Suzette face Yolanda, but she brazenly denies the allegations.
Despite her rising fame, culminating in a record-breaking concert at the Houston Astrodome on February 26, tragedy strikes just a month later on March 31. After a heated dispute over the missing funds, Selena is horrifically shot by Yolanda at a motel in Corpus Christi. Following a standoff, Yolanda is apprehended by the police. The devastating loss sends shockwaves through Selena's family, friends, and fans, culminating in a poignant candlelight vigil where a montage celebrating the life of the real Selena plays, providing a bittersweet farewell to an extraordinary talent.
