Sibi who is a police officer gets injured while trying to rescue a kidnapped girl and he is asked to take rest. He lives with his wife Arundhathi and his sister. A military-trained dog named Mani is given asylum in his neighbour’s house.

The neighbour citing a visit to hometown requests Sibi to take care of the dog for a few days. Sibi refuses the request and therefore the owner leaves the dog in a cage in his premises. Sibi happens to save the animal from being disturbed by some children and takes it to

his home. Then he hears the news about his neighbour’s death and becomes more affectionate towards the dog after knowing that it is military-trained.
 
When Sibi returns to his work, his wife Arundhathi is kidnapped by a mysterious gang. The gang leader Balaji threatens Sibi for ransom.

Moreover they bury Arundhathi alive in a coffin and informs that she should be saved within six hours. Whether Sibi is able to save his wife or not is the rest of the story.

Sibiraj makes his come back after a long break and this seems to be an important film for him. He fits well in the role and has given a natural performance. Arundhathi though given a small portion has done it perfectly.

The dog Mani plays the main character and bags the applause of the audience. A special appreciation can be given to the trainer of the dog. Knowing that success needs something other than the story and the hero, director Sakthi Soundar Rajan has made his screenplay interesting by focusing the dog as the main character.
 
The songs are pleasant in Dharan's music. Nizar Shafi's cinematography enhances the thriller feel.
