C.I.D. Shankar

Starring South Indian cinema James Bond, Jaishankar, C.I.D. Shakuntala (after this movie), venniraadai Murthy, Manoharan, O.A.K. Devar, thengaai Srinivasan, V.S.Raghavan and others, the movie is about the mission of solving political murders.
The movie opens with a gang drugging women to become human bombs and kill political leaders.
The police division is out to hunt this group down. C.I.D. Shankar is out to catch them. He and his assistant reach the location to be diverted by the villains, but they escape.
The cop on duty prior to them is fatally injured. Shakuntala saves him, but he dies. While investigating the dead man's apartment, Shakar meets with his sister and asks her to be careful.
Bit by bit Shankar moves closer to the gang. On the way, many lives are lost. Finally, Shakuntala's brother offers to help. When they reach his house, they leave to meet his friend, who is a plant researcher and he tells Shankar about the drug that the group uses and then takes them to the location. The group finds out that it was a trap. They are held in their prison.
When Manohar realises that his ideals are not the same as that of the group, he starts helping Shankar out and the last 30 minutes was them getting the bad guys.
The last 30 minutes was grueling to sit and watch since the ending was pretty clear. Also it seemed like the story was disjointed in many places and sometimes there was underacting. And some bits seemed ridiculous - like the bad guys messaging on the roadside 'secretly' with their machines totally in the open. It was a tolerable movie to watch, although I would have let it pass.
