It's 2005. A van full of people traveling from Navamalai to a city nearby is forced to take a detour through the village of Kattiyal. The van goes missing in the forests, leaving Sakthivel and Karunagam bereft with grief at the loss of their children. In the present day, Gautham and his family set off on a road trip one fateful night when a detour down the same route changes their lives forever.
