Duraisingam goes undercover to find out the international don behind these alleged activities in Thoothukudi where he pretends to be as an NCC teacher at a school. Sooner he unearths a dangerous criminal network and sets up 'Operation D' to nab international drug dealer Danny. How he deals with all this? That is how the story deals.
Director Hari has designed Duraisingam for his mass audience which is clearly seen in the flick. He has reloaded the old version to strike gold. He might be successful in this but he partially entertains with this drama.
You will find 'n' number of loopholes in the flick but still the desire to witness south superstar Surya will force you to stay in.
