The murder was made up as a suicide by the criminals. Four of Tamizhmani's subordinates are suspected: his comrades-in-arms who said they were his friends. Tamizhmani's name banished forever, and his family was delivered to the vindication of the people, who set their place of residence on fire, in reprisal. Tamizhmani's son Anandhan, informed of his origins, starts an investigation to restore his honor and find the real culprits.

Reception
