Nonton Adanga Maru (2018).A sincere cop, who’s suspended from the department for locking horns with a few influential people in the society, starts taking revenge against those who finished off his dear ones.
Subhash (Jayam Ravi) is an upright and sincere Sub-Inspector of Police in Chennai. He resides with his father (Ponvannan), mother (Sriranjani), elder brother (Subbu Panchu), his wife, and their twin girls. He is all set to marry his fiancée Anitha (Raashi Khanna). He is new to his job and is assisted by Constable Ramadass (Ramdoss) and SI Chandran (Azhagam Perumal). Subhash cannot stand the suffering of the public and looks for ways to better their lives, and this often lands him in trouble with his superior Inspector Muthukaruppan (Mime Gopi).
One day, Chandran and Subhash are called on to investigate the supposed suicide of a girl. On closer investigation, Subhash deduces that it was not a suicide and that she was murdered. While collecting evidence to support this, he comes across a person called Abhijit (Bharath Raj), whose cell number was active near the place. On confronting Abhijit and his friends Christy, Bhuvan, and Deepak, they reveal that they are all stoners from affluent families and show a video of them doing drugs, raping and murdering the girl and many other women, as well. Subhash gets enraged, beats them up, and locks them in jail. When his superior, a corrupt Joint Commissioner Saarangan (Sampath Raj), asks for the proof behind his accusations, he finds out that the phone had automatically deleted all the video files just as he was trying to unlock it. The four are released due to lack of evidence and the influence of their respective fathers and Subhash is suspended. Abhijit and his friends vow revenge and soon enough, when Subhash goes home, he finds his parents and brother’s family dead. Only one of his nieces, Anusha, is left alive. Meanwhile, Saarangan is bribed with a Porsche car and reports the murder of Subhash’s family as a fire accident at their new house. Dejected at his powerlessness even though he is a police officer, Subhash resigns and threatens Saarangan that he will avenge his family’s death and will make sure that the four guys die mercilessly at the hands of their own fathers.
