It seems there might be a confusion or a mix-up regarding the synopsis or title. As of my last update in January 2022, there is no widely recognized movie called "Kofa" that matches this specific plot description. However, I can certainly help outline a plot based on similar themes that you might be interested in:
Imagine a psychological thriller where eight individuals wake up in a locked room with no memories of who they are or how they got there. As they explore their surroundings, they discover clues that suggest they have a shared past that has been intentionally erased. Soon, they realize they are being hunted by a mysterious, masked figure who seems to know more about them than they do themselves.
As the group tries to piece together their identities and unravel the mystery of their confinement, tensions rise as suspicions and paranoia set in. Each member of the group has skills and knowledge that could help them escape or uncover the truth, but they must navigate their growing distrust of each other amidst the imminent threat of the murderer.
Throughout the movie, flashbacks and fragmented memories slowly reveal the interconnected lives of these individuals before they lost their memories. They begin to understand that they were brought together for a reason, possibly connected to a dark secret or a crime they committed or witnessed. As they race against time to evade the killer and unlock the door to freedom, they must confront their own pasts and the consequences of their actions.
Ultimately, "Kofa" could be a gripping tale of survival, identity, and redemption, where the true enemy might not be the masked murderer chasing them, but the secrets buried within their own minds. If you have specific details or themes from "Kofa" that you'd like explored further, feel free to share, and I can tailor the storyline accordingly!
