The Midnight ShiftSeon-ran Cheon2021

When four isolated elderly people commit suicide back-to-back at the same hospital by jumping out of the sixth-floor window, Su-Yeon doesn’t understand why she’s the only one at her precinct that seems to care. Dismissing the case as a series of unfortunate events due to the patients’ loneliness, the police force doesn't engage. But Su-Yeon doesn’t have the privilege of looking her dearest friend, Grandma Eun-Shim, lives on the sixth floor, and Su-Yeon is terrified that something will happen to her next.

As Su-Yeon begins her investigation alone, she runs into a mysterious woman named Wanda at the crime scene. Wanda, hot on the trail of her ex-lover, Lily, gives Su-Yeon the answer to her a vampire did it. Su-Yeon is skeptical at first, but then a fifth victim jumps from the window and her investigation reveals the body was completely drained of blood. Desperate to discover the cause of the deaths, Su-Yeon considers Wanda’s explanation—that something supernatural is involved.
