All 11 episodes of the detective serial set and recorded in Mumbai.

Inspector Alia Khan is a tough, determined female cop struggling to make her mark in a male-dominated world. As she fights to uncover crime and corruption, she must also battle the endemic sexism of the police force and the patronising, chauvinist attitudes of her boss and colleagues - as well as dealing with her own personal demons.

In series one, landed with a new partner, she investigates a rescued baby, a missing husband, a child prostitution ring and strange goings-on at a psychiatric hospital. When a glamour model is found dead in a five-star hotel, she sets out on the trail of Bollywood's leading heart-throb, and uncovers murder, political scandal - and the truth about her policeman father's death.

In series two, the disgraced police inspector has just been released from jail. Seeking a life of obscurity, she gets a job as a receptionist in a run-down Mumbai hotel. But when a serial killer starts operating on the rooftop, Alia is called in. Paired up with incompetent Inspector Ratna Shinde, she soon realises that the murderer is trying to communicate with her through the victims themselves....

Series three finds Alia going undercover after suspicions are raised about a young woman's death. When Nyla Ansari is found in a bathtub in her parents' home, a bottle of pills beside her, it looks like suicide. Then a video is discovered, made by Nyla a year before. In it, she claims her father, a wealthy Indian businessman, was going to kill her. Posing as a newly married couple, Alia and her male colleague Junaid Qureshi move into the flat next door. Their mission: befriend Nyla's family, friends and servants, and find out the truth....
