While Detective Dhruva is awaiting response to his ad' for a lady assistant, Inspector Shakeel comes to seek his help in pinning down Radha who he suspects had poisoned Madhu her man and Mala his mistress. But before Dhruva could grapple with the issue, Ranjit comes to seek his help in facilitating the release his kidnapped wife Kavya, who only that morning, had posted her bio-data to him.
Dhruva recruits Shakeel to ingeniously rescue Kavya but to cynically implicate her captor, the young Pravar, in a fake currency case. But that only accentuates the empathy Kavya, a lawyer herself, experiences for Pravar courtesy the Stockholm Syndrome. She manages to secure bail for Pravar by putting Shakeel who she believes was behind it all in the dock. Pravar who develops an eye for the mature Kavya schemes to win her over unmindful of his wife Natya's protests. When in the end, Kavya capitulates; he begins to press her to divorce Ranjit.
In the meantime, Radha the suspected murderess tells Dhruva that it was Mala's brother Pravar piqued by her affair with Madhu who could have poisoned them both. When Radha seeks his help to expose Pravar and rescue her honour, Dhruva takes her on board as his assistant. Shortly thereafter, Ranjit was poisoned to death presumably by a burkha-clad woman whom he was receiving at home when Kavya was away with Pravar. Before Shakeel could grapple with the murder case, he himself was poisoned to death deepening suspicion about Pravar's role in the murders. But Pravar and Natya died of poisoning in Kavya's home when she was not in town, allegedly by a burkha-clad woman.
While Radha articulates Kavya's motive to murder each one of them, Dhruva thinking that there was more to the murders than met the eye, begins to probe the crime on a different plane. In the end, when he leads Inspector Simon who succeeds Shakeel towards the culprit, it leaves Radha and Kavya equally surprised .
Dhruva, impelled by all that, stood engrossed, and Raju, the housekeeper, fetched him a plateful of hot pakodas, which, facing the spatter, he began to savour, and before he had finished with the snack, Raju returned with a mug of steaming Darjeeling tea for him. Soon, the refreshed sun resurged to warm up the leaves, even as the satiated roots let the bounty go down the drain. Done with the beverage, Dhruva picked up the sachet of lanka pogaku, to roll a cigar, and finishing that as he reached for the cigar lighter, the rainbow, in its resplendent colors, unfolded in the misty skies. However, when he began puffing away at the cigar, as if dispelled by its strong scent, the dissipated clouds began disappearing from the horizon.
Watched by Dicey, the Alsatian, Dhruva savored the cigar to the last puff, but as he stubbed the butt, and stepped out onto the lush green lawn, the pet followed him to leave its footprints on the damp canvas in its master's tracks. Even as the clouds began regrouping in the skies, he covered the garden to caress every croton and coleus as he would Dicey. But when it portended downpour, Raju led Dicey into the portico and Dhruva headed towards the study to pick up the half-readCrimes Digest of the month. However, as it rained again, he reached the first-floor French window, standing by which he thought that it was akin to the urge of the assassin to revisit the scene of the crime, for a review of the same. Amused by his analogy, he thought as if the rain was obliterating its earlier footprints, but when it ceased raining and the skies turned murky, seemingly mourning the loss of their resplendence, he too immersed himself in the dark world of crime theDigest pictured.
Meanwhile, Raju let Dicey do the patrolling, and soon it began barking at the gate inducing Dhruva to reach to the window, through which he saw a sensuous woman, tentative at the half-open Iron Gate of his mansion. Enamoured of her attractive face and desirous of her middle-aged frame, as he stood rooted, the pet sprang up to the gate, forcing the tantalizing trespasser to beat a hasty retreat. No less affected by her sensual gait in her retreat, Dhruva lost his eyes to her, until she went out of his sight, but readily alive to her loss, he cursed himself for not sticking to the portico. Inexplicably obsessed with her, he rushed to the gate only to see her turning the bend even as Inspector Shakeel came into view on his Bajaj Pulsar.
When Shakeel greeted Dhruva, feeling lost, he forced himself to hug him, just as Dicey leapt up to the visitor in welcome, and as Raju took away the pet, Dhruva led the cop into the portico, wondering aloud what made him scarce, for nearly three months then. When Shakeel began to detail how he had reached the dead-end of the investigation of a double murder he was handling, the detective closed his eyes, as if to avoid reading the script from the cop's body language.
