Senior High (TV series)

Luna’s death sparks a scandal at the prestigious Northford High. Though officially ruled as a suicide, her twin sister, Sky, believes there’s more to the story. As she investigates, Sky uncovers disturbing truths, revealing that those around her are entangled in lies and hidden desires. Throughout the school year, Sky discovers unsettling details, including a video showing Z bullying Luna. Shocked, Sky confides in her mother, Tania, who is devastated by what Luna endured. Meanwhile, Archie learns that Harry is the biological father of Sky and Luna and shares the news with Sky after a drug-related incident. The school is soon put on high alert due to illegal activities involving Obet. Harry’s troubled relationship with his second wife, Sasha, is exposed, as she briefly leaves him before returning after a settlement.

As Sky, Obet, and Lydia search for evidence in the school’s CCTV footage, they discover suspicious activity. During exams, Kenjie frames Sky by throwing a cheat sheet at her, leading to her expulsion. However, the evidence is overturned, and Kenjie apologizes to both Sky and Sanya, restoring their friendship. Sky is allowed to retake her exams and passes. At Sanya’s birthday party, Z attempts to humiliate Sky but is thwarted thanks to witnesses like Obet and Kenjie. As Sky grows closer to Gino, she remembers her late sister, Luna. The following day, Principal Amanda informs Sky that her tuition is unpaid. Meanwhile, rumors spread that Luna was pregnant, allegedly with Gino’s child, leading to a scandal that shakes the community and damages Gino’s reputation.

William dismisses Harry for mishandling the situation, while Lydia uncovers that her son, Tonio, has escaped. Harry soon learns that Darius Soledad is Tonio’s boss and discovers that Sasha is cheating on him with Darius. Tim wrestles with his feelings for Poch, while his parents, Edith and Elmo, struggle with marriage issues. Sky insists on DNA tests to determine Luna’s baby’s father. Gino agrees, but his parents block him from participating. William manipulates the situation, while Gino’s mother, Cecille, urges him to flee after William becomes violent. At the same time, Mr. Castrodes claims to be Luna’s baby’s father, adding to the chaos. As tensions rise, Poch reveals that William was his sugar daddy and warns Tim, who narrowly escapes an attack ordered by William. Sky, Tim, and Obet uncover shocking evidence linking William and Mr. Castrodes to illegal activities, including sexual trafficking. William’s attempts to cover up his crimes fail, leading to his arrest. However, the trauma continues as Luna's ghost haunts Z.

As graduation approaches, the truth behind Luna’s death is finally revealed: Acosta was the one who pushed Luna from the building. The incident happened after Luna and Z had a confrontation because of Acosta. Luna, who was pregnant with the governor's son Gino, asked Z to stop bothering her or else she will reveal that she witnessed Acosta's abuse to the latter by grooming her. Acosta then found Luna and Z on the veranda, and after Luna confronted and threatened him because of what he did to Z, he strangled and pushed Luna from the building. Z, manipulated by William, gave a false alibi, framing herself as Luna’s killer. In the climax, William attempts to kill Z, but Harry sacrifices himself to save her. Sky confronts William on the rooftop where Luna died. In a final struggle, William falls to his presumed death. The nightmare seems to be over as the students and their families begin to heal, though scars remain.

At graduation, the Northford seniors celebrate their accomplishments while mourning the losses of Luna and Obet. In a surprising twist, William is revealed to have survived the fall and awakens with a renewed thirst for revenge, an unseen visitor gives him the details concerning Sky's whereabouts. Thus, it gives way for a new era of a menacing nightmare and a new era of horror.
