Chow Mei Si (Diana Pang) is a late-night radio DJ who receives an ominous warning from one of her callers. The caller, named "Hungry Wolf", says that he's going to blow up a hospital...and he does! Chow Mei Si tries to warn cop Wong Chi Ming (Michael Wong), but he's skeptical. That is, until the caller threatens to blow up a kindergarten and promptly follows through. Now Wong and his partner (Joyce Ni) must protect Chow Mei Si from the bomber before he can claim her as his next victim!
Unfortunately the movie Midnight Caller is not yet available on HBO Max.
