It's a one man show. You only get to see one person throughout the movie. In the middle there's a little kid on a video call which lasts for 2-3 minutes & at the end there are 3 cops for few minutes. The whole movie is just a phone calls from his wife, mom, sister & other people.
It was listed under 'Horror' genre, but honestly there wasn't anything scary or thrilling happened till the end. I have no clue why did they name it 'Bannerghatta' when the story isn't even related to that place. They did put unnecessary scenes at the end just to create a crime scene more interesting but couldn't do it. Only the lead actor deserves appreciation for his expressions. Sorry but I won't recommend this to horror fans. 🤷♀️
