Sadhasiva "Sadha" Pandian is a siddha doctor who practises his medicine in Kodaikanal, the same town where Surya joins in as hotel manager, and police officer Parasuraj takes in-charge at the local police station. As Sadha and Surya, who come with their own fair share of trauma, bond and get closer to each other, it does not seem to sit well with Parasuraj whose villainy nature comes to the forefront with a seemingly visible connection he shares with Sadha from past.
