It premiered on Hong Kong's TVB Jade and Malaysia's Astro On Demand on April 11, 2016, airing Monday through Sunday during its 9:30-10:30 pm timeslot.

The fictional show is about nine immortal humans who fight against vampires.

Plot
500 years ago, ten members of Kam-Yi-Wai took an order to kill a group of vampires of unknown origins. All except one were killed by vampires. After the vampires left, the nine Kam-Yi-Wai's dead bodies were struck by lightning and turned into super powered immortals.

In the present, the nine immortal humans hide amongst the people, seeking and killing vampires. They believe that they could be mortal again if they kill all the vampires.

Lam Mung-Nam is a vampire that has been trying to be a human for a decade. She hides in the Lam family, residing with her human sister, Lam Mung-Yiu, whose parents were killed by vampires, causing her not to speak anymore, and her grandmother, Wong Chi-Hung.

The grandmother, Wong Chi-hung, rescues three youths who are searching for vampires in the Netherlands. One of them, Ghost Yau Ling-mui, steals a ring from the vampiress Xenia's tomb. While they are back in Hong Kong, some supernatural things happen. Ghost gains a mind reading ability, and a stomachache. Xenia wants them to return the magic ring and claims that it is a family heirloom, and she is responsible for its safekeeping.

Ghost's best friends, Ho Nin and Ho Yuet, are students from a martial art school, Ceoi-Yi School. Its creator and founder Kam Kin learned martial art skills from one of the nine undead-humans, Ying Wut-Zoek (who at the time was calling himself Ying Zoi-sang). Kam Kim also has a student called C Kwan who works with Mung-Lam as a forensic medical doctor.

After Kam Kin dies, he passes his students to Ying Wut-zoek, asking him to take care of them. Ying Wut-zoek then trains them to be vampire hunters.
