1999 Manila, Philippines. Ms. Pat (Bea Alonzo) works as the guidance counselor in a conservative, all-girls, Catholic high school. Secretly a clairvoyant, Ms. Pat waits at her desk every night for midnight therapy sessions with the ghost of Eri (Gillian Vicencio)– a student who committed suicide in the school grounds more than a decade ago. Her routine is shattered when a student is found murdered on campus. The murder is quickly pinned on the school groundskeeper, the only male employee on campus. He admits to the murder despite no clear motive. Ms. Pat suspects the true culprit to be the feared Sor Alice (Charo Santos), the school's tyrannical Mother Superior. Julian (Jake Cuenca), a police investigator, enlists the help of Ms. Pat to uncover clues from the secretive students. Sor Alice, satisfied with the previous findings, proceeds with the victim’s memorial. With no living witness, Ms. Pat turns to the sole watcher of the school – Eri.
