Radhe Mohan Sharma, a railway ticket checker, stumbles upon a minor discrepancy in his bank account, setting off a chain of events, leading him to uncover a massive financial fraud orchestrated by a powerful banker named Micky Mehta, the founder of Do Bank. While unearthing a billion-dollar scam and facing immense pressure and threats, Radhe does what it takes to expose the truth.

Have you spared a minute to check if your bank balance has an insignificant discrepancy? Would you invest precious time and energy to make the bank accountable for Rs 27.50? It’s precisely this common customer lethargy that makes suave and merry Micky Mehta (Neil Nitin Mukesh) make dizzy sums like Rs 20,000 crore. Small amounts that don’t tally, interest credited just a day later, inconsequential figures that account holders ignore. Micky preys on just this customer ignorance to live life like a party. But there’s always one aam insaan whose brain works like a calculator. Senior Ticket Collector Radhe Mohan Sharma (R Madhavan) arrives laden with oranges that he generously shares with passengers. “I don’t touch stolen goods,” huffs passenger P Subhash (Kirti Kulhari). His enthusiastic reply about taking oranges to balance what the fruit seller owed him as change, delightfully introduces Radhe’s quirk. Debits and credits must tally. He’d once rejected a marriage proposal too because the girl was weak in Maths.
