The film belongs to the gritty crime action and drama genre of the Nepali cinema that tells the story of the underworld, gang war and double-crossing city.

The story of the film is the series of events of the Nepali underworld: Kalu Yadav is a young man of the criminal world who frees his friend Vicky from the prison, and both start working under a crime boss named Raja. A police raid ruins the drug deal of the boss, and Kalu suspects the rival gangster Bhalu of tipping off the police. Meanwhile, Salina, the girlfriend of the boss Raja, is secretly cheating on him with Vicky. Kalu becomes the main suspect in the murder of a builder, and he is under pressure from the angry boss. After realizing that Bhalu revealed his boss's activities to the police, Kalu kills Bhalu, but Raja abandons him; in hiding, Kalu allies with the Malik Bhai and plans the elimination of the boss. Vicky and Kalu together murder Raja and bury his body in the empty ground, but the money that Vicky gives Kalu turns out to be fake; the fight breaks out between the two partners, and the crooked DSP kills them both, revealing at the end that Salina - the woman they both trusted - planned everything to take the Raja's property and run away with another man.

The film is the representation of the brutal crime world of the city - money, power and betrayal - and it is made in the style of the tough action films with the fight scenes and the suspense of the plot. The film's main interest lies in its construction and the twisted story, where the two friends of the brothers are turned against each other to discover that they have both been manipulated by the one person they truly trusted: a theme of the thriller that was fresh in the Nepali action cinema of that time.

With the strong cast - particularly the actors Saugat Malla, Vijay Lama, Anup Baral and Priyanka Karki - and its dark and suspenseful tone, Sadanga remains one of the notable crime action films of the Nepali cinema of 2015, appreciated by the audience of the genre for the tension and intensity of its performances.
