Ms. Pat (Bea Alonzo) works as a guidance counselor in a conservative, all-girls, Catholic high school. Secretly a clairvoyant, she waits at her desk every night for midnight therapy sessions with the ghost of Eri, a student who committed suicide on the school grounds more than a decade ago. Her routine is shattered when a student is found murdered on campus. Suspecting the culprit to be the school's fanatical overseer Sor Alice (Charo Santos), Ms. Pat turns to the sole watcher of the schoolEri.
