Dhaya (2002)

Despite repeated warnings from a concerned neighbor (Meena), a good-hearted woman who runs an orphanage (Lakshmi) refuses to believe that her seemingly harmless new driver (Prakashraj) is actually part of a plot to discredit her. But the awful truth is that a powerful ex-army man (Raghuvaran) who's determined to settle an old score has hired a thug to infiltrate the orphanage and orchestrate the owner's downfall.
