Siruthai

A little girl walks up to Rocket Raja (Karthi), a petty thief with a nose for easy marks, and calls him her father. The truth turns out to be his lookalike, the honest cop Ratnavel Pandian, and Siva sends Raja after the local gang that Pandian's badge was made to fight, with Santhanam along for the jokes. Under the chases and the noise, a child's belief in a stranger is what pushes a thief toward being a better man.
