Bepin Babu encounters a man named Parimal Ghosh who claims to have knowledge of a trip Bepin took to Ranchi in 1958 that Bepin no longer remembers. This troubles Bepin as he is sure he has never been to Ranchi. Parimal provides details about the trip that seem accurate, including a scar on Bepin's knee. Bepin decides to call his friend Dinesh Mukerji, who Parimal said was in Ranchi at the time, hoping to resolve the confusion over whether he actually took a forgotten trip or is losing his memory.
