When a murder is committed in Sunflower Society, all the residents come under the radar of the investigating officers. But due to his antics, Sonu Singh becomes a suspect.
While Officers DG and Tambe probe Sonu, Mr. and Mrs. Ahuja try to get rid of the evidence. Later, Mr. Ahuja lands in an awkward situation which is likely to get him caught.
A delivery boy divulges important information which links Sonu to Kapoor's murder. When DG probes Ahuja, he pretends to be calm and composed. Meanwhile, Sonu manages to strike a conversation with Gurleen.
When Tambe finds some intriguing CCTV footage, he interrogates Kapoor's maid Kamini. The coconut seller reveals that he had delivered a coconut at Kapoor's house.
Sonu sells a box of unused syringes, creating further complications for himself and is picked up by Tambe for interrogation. Impressed by Sonu's bad boy image, Aanchal asks him for a night out.
Sonu wakes up in Justina's house in just his underwear and is clueless about how he reached there. While sneaking out, he spots his boss and jumps into the house of an old neighbour who is having a heart attack.
Sonu takes the old man to the hospital and looks after him. Tambe reaches Kapoor's brother's house and finds Kapoor's ex-wife living there. While DG finds clues against Ahuja, Tambe gathers proof against Sonu.
DG digs deeper and discovers Sonu's motive behind Kapoor's murder. Oblivious to the fact that he has been declared the prime accused, Sonu ends up in a whole new mess.
