Despite several shortcomings, the spy thriller starring Karthi is interesting and enjoyable partly thanks to some outstanding action and the lead actor. You should take PS Mithran seriously since he strives to consistently push the boundaries of filmmaking. Irumbu Thirai, a fantastic cybercrime thriller that was his breakout debut, was followed by Hero, a critically praised superhero thriller. With Sardar, a somewhat absorbing spy thriller that tackles a very acute matter, Mithran now makes a notable comeback. Karthi plays inspector Vijay Prakash, a media exposure character who would stop at nothing to create headlines. His serious efforts have caused Tamil Nadu Police to become a frequently discussed subject on social media. Vijay's dedication to his career, however, is compromised by the fact that his father was a former spy who has been labeled a traitor by the government.
