Bhavani (Mukesh Rishi) and Narsimha (Jayaprakash Reddy) are sworn enemies, each of whom hates his toes being treaded on by the other. But it's something they can't help doing - like inadvertently slapping a mosquito on your cheek. It's just as reflexive and ordinary an act, and as painful to the men as it is to the mosquito. And to the audience as well.
Of the 2 men, Bhavani is supposed to be cleaner than Narsimha, since he's some kind of local benefactor who people run to when they have issues. Narsimha, on the other hand, is the issue many people have.
