Cobra (2022) Tamil

A Turkish Interpol officer, Aslan Yilmaz, investigates the assassinations of the Chief Minister of Odisha, the Mayor of France and the Prince of Scotland, where he, with a young Tamil criminologist Judith Samson, deduce that Cobra, a skilled assassin, is the mastermind behind the assassinations. The duo learn that Cobra perfectly assassinates his targets using mathematical skills, leading them to believe that the master assassin is a professor of mathematics. Meanwhile, Mathiyazhagan, "Mathi", a mathematics professor, who is actually Cobra, receives his next assignment from his mentor and senior journalist in Kolkata, Nellaiappan. He is to kill the Russia's defence minister, Dmitri Yugolsav. He travels to Russia, successfully assassinates him and escapes, despite tight security from the Interpol and Aslan's plan that almost trapped him. Before Yugolsav's assassination, Aslan and his team watch a telecasted conversation between Nellaiappan and Nawab, who works at a company named Rishi Corporation, where he concludes that the victims connect to the company's owner Rajeev Rishi, a psychotic and sadistic business magnate, who inherited the company from his father. Rishi runs a criminal syndicate, who targets people who oppose his company. Following the engagement to his criminologist girlfriend and Judith's teacher, Bhavana Menon, Mathi learns that someone has kidnapped Nellaippan and discovers they are targeting him from the beginning of his assignments. After a clue from Sudoku, Mathi receives a call from the person, who is Mathi's doppelgänger, where he challenges Mathi to save himself from him. An unexpected turn of events reveals Mathi to be Kathir, Mathi's schizophrenic long-lost twin brother, and the doppelgänger who challenged Kathir is the real Mathi. Rishi sends men to capture Mathi, but Kathir manages to kill them. Mathi had been holding a grudge against Kathir, as he was responsible for the death of his girlfriend, Jennifer Rosario.
