Police Inspector Ghote lives a middle-class life in Bombay along with his wife, Pratima. He has been employed with the Bombay Police for many years. His wife is generally disgruntled and wants a better life. He is assigned to investigate the deadly assault on a Parsi man named Perfect, who is the Secretary of Lala Heera Lal, a wealthy man with underworld links. Inspector Ghote commences his investigation and is displeased when his superiors ask him to work with a Swedish Forensic Expert by the name of Axel Svennson. Axel is thrilled to get a closer look at the working of the Bombay Police, but also realizes that Ghote may not be one of their best police officers. When their friendship develops, he gets invited to Ghote's house, and gets to meet Pratima. Their investigation, though Prima Facie simple enough, takes them through turns and twists that both had not expected - including corridors of power and corruption - and finally to the conclusion and the unmasking of the culprit(s) behind this incident.
