Vaishak, a computer engineer, lands in Kochi from Dubai on March 19, 2020, just three days before the Janta Curfew, with many things to do before taking the Duronto Express to Mumbai the same evening to meet his love, Revathy. He was supposed to leave back in a week. During the day, he had planned to catch up with his hostel roommates, Sudeep and Cherian, and also meet the person for whom he had purposefully made this visit from Dubai. He also wanted to meet Ajay Sethuraman in this visit, to whom he had sold his large rubber estate a few years back in order to pay for blood money and save his mother from being hanged in Saudi Arabia.

His friends and old associates don't know who he is now, and his current associates don't know his past.

However, the train journey doesn't turn up the way Vaishak had planned. He finds his past and present intertwining with each other and comes haunting after him in the journey. He wasn't ready to give up and ensures that the truth shall find its way, and he does what he was best at - he was a cryptocurrency miner.
