Inspector Heera Lal and Havaldar Panna Lal are two simple-minded but honest policemen, who serve at the local police station.

Then their lives are turned into utter turmoil and hilarious chaos, when they find out that another pair of men, also named Heera Lal and Panna Lal, who are their look-alike, have entered the same town they live in.
