The film revolves around a single day in 'Hill Top' - the once-grand, now-drab hotel in downtown Ernakulam, where a constantly bickering married couple, Pavithran and Haripriya, checks-in for a jolly stay. All the hotel employees and residents seem odd from the beginning itself. Then, all of a sudden, a resident shows up dead under some mysterious circumstances. Now, everyone's a suspect.
