Official trailer and plot of Sumathi Valavu

Sumathi Valavu is set on a street that is infamously believed to be haunted. According to local lore, the place is where a Tamil woman named Sumathi met a tragic end, and henceforth her spirit is said to be the cause of supernatural activities in the area.

When a group of youngsters ventures onto the street, they begin to experience disturbing and eerie instances. What are the mysteries surrounding the place, and how will they overcome the challenges form the crux of the story.

Interestingly, Sumathi Valavu is inspired by a real location in Mylamoodu, Thiruvananthapuram, Kerala, with the same name. As per urban legend, a woman named Sumathi, who was pregnant at the time, was murdered by her lover in the 1950s at the very same spot.

Since then, locals have claimed the place to be haunted by her spirit and have associated it with various supernatural occurrences.

Additionally, some reports suggest the location was exploited by criminals who created the facade of a supernatural entity to cover up their illegal activities.
