The opening scene of Episode 1 of Delhi Crime Season 3 unfolds at a festive community wedding, where a young girl's destiny is being forcibly altered as she is pressured into marrying a much older man. Her refusal to accept this arranged marriage leads to her being abruptly whisked away, replaced by another innocent girl.
The narrative shifts to Assam, where Deputy Inspector General Vartika embarks on an investigation into a weapon-smuggling operation. However, her quest for the elusive truck transporting weapons is abruptly interrupted by a suspicious vehicle that halts near the checkpost. To her surprise, the truck reveals a chilling truth—it's brimming with young girls being smuggled for sex trafficking, bound for Delhi from Mizoram. The truck driver, with a heartless demeanor, reveals the girls' intended destination.
Vartika urgently informs the police chief of the grim reality behind these girls' captivity, under the false promise of job opportunities. The cop reveals that one more girl, Sonam, has gone missing after being promised a tutoring job in Delhi. Vartika immediately reaches out to Bhupendra in Delhi, requesting him to keep an eye out for the missing truck with eight girls, including Sonam. She expresses her need for permission from the Director General of Police (DGP) to embark on an investigation in Delhi.
Meanwhile, Neeti encounters her ex-husband Devinder and his wife Mallika at a friend's house. Neeti receives a call from Vimla, informing her about an infant found at AIIMS with severe injuries and brain trauma. Neeti dives into the case of the baby girl, who was left at the hospital by a young girl. Her team sets out to find the girl, and Jairaj and Sudhir track down the auto driver who dropped her off. The driver reveals that he picked her up from a lodge.
Vartika travels to Mizoram to meet Inspector Krishnamoorthy, who reluctantly refuses to sanction an interstate operation due to financial constraints. Vartika persists in her pursuit, pleading for written consent to delve into such a high-profile case.
In parallel, Sonam and the other girls from the first truck are sent to Delhi. Kalyani engages with the girls, urging them to present themselves more attractively by applying makeup. Meanwhile, Rahul, the man who transported them, receives a call from his wife and makes his way home. Kalyani receives a call from Didi, inquiring about the two trucks sent from Mizoram.
The police pursuit of the woman who abandoned the baby unfolds as Khushi and her husband, Rahul, find themselves at the center of the investigation. They sift through the lodge room's interior, uncovering a trail of bloodstains that lead them to a chilling realization. Inquiring neighbors provide a glimpse into their lives, while Rahul, spooked by the authorities, makes a beeline for the lodge but flees when he spots the cops on his tail.
Meanwhile, Didi embarks on a rigorous training regimen for her girls, preparing them for their impending international buyer, John Gupta, and expedites their passport processing. Her partner confides in her that the loan shark Bhaiji's debt is a heavy burden to bear. Vartika arrives in Delhi, escorted by Bhupendra to the station.
Khushi calls Rahul, confessing that she left the infant Noor at the hospital. Rahul's efforts to soothe her are cut short when he learns of Noor's critical condition and ongoing surgery. Neeti and her team dissect the case, concluding that Rahul must have inflicted harm on the baby. She dispatches Vimla and Jairaj to wait at the hospital, braced for any attempts by Khushi or Rahul to retrieve Noor.
Sudhir dives deep into Rahul's past, uncovering his attempts to assault a 12-year-old girl that led to his termination from a car repair shop. CCTV footage captures Rahul attempting to force Khushi into a car outside the hospital, an act that Vimla promptly reports to Jairaj, igniting a chase that sees the couple on the run. Rahul tries to escape but abandons his car in a secluded street. He urges Khushi to flee but she remains trapped inside. As Rahul escapes, Khushi is taken into custody.
Vartika and Bhupendra delve into the trail of the first set of girls' transportation, seeking out the travel company behind their vehicle. The episode concludes with Didi introducing Sonam and two other girls to John Gupta, as if the stakes couldn't get any higher.
