Luna bears the brutal memory of her past life, when her stepsister Catherine pushed her straight into the path of the Sound Chasers.
She travels back in time to the day her family goes bankrupt.
As her stepsister fights fiercely for the luxury penthouse in the city center, Luna deliberately chooses an abandoned underground supermarket in the suburbs.
With a three-day doomsday countdown ticking away, she frantically prepares and lays out her survival plan.
When the auditory apocalypse descends, the Sound Chasers hunt by chasing every sound.
Catherine and her mother are trapped in a desperate plight inside the fancy mansion, while Luna lives safely in her Silent Paradise.
Faced with the greedy Alan gang and her constantly self-destructive relatives, she uses the Sound Chasers as her blade and deadly traps as her shield.
All those who try to drag her into hell end up buried by their own desires.
This is a thrilling revenge survival game ruled by time regression and perfect premeditation.
