In the 60s...

A military officer (Sathyaraj) is accused, inequitably, of giving intelligence to the enemy, during an operation, code named Day Break.

He is later murdered, before he can bring out the truth. The murder was made up as a suicide by the criminals.

Four of his subordinates are suspected, his comrades-in-arms (the traitors of the story) who said they were his friends.

The name of the serviceman is banished forever and his family was delivered to the vindication of the people, who set on fire their place of residence, in reprisal.

His son (played also by Sathyaraj), informed of his origins, starts an investigation of his father, to wash his honour and find the real culprits...

The film has an intuitive story line with Sathyaraj enacting a dual role. The role of an army officer was appreciated by the critics.
