Keerthy, a PG student in forensic science, is our central character. At one point, she gets to be a part of a case where the police recovered the remains of a body in a concrete-filled container that was buried four years ago. After the examination of that body, certain unnatural events start to unfold around Keerthy, and she is led by some force to find the mystery behind this particular case. How that unravels is what we see in Hunt.
