A group of people attempt to rob a bank, but they are caught off guard when another person arrives with a plan. Authorities work to apprehend the robbers and free the hostages. slowly discloses the protogonist's flashback, which was the inspiration for the bank robbery... In conclusion, critique bank frauds. Message is good, but not very powerful. Heroics done in excess and undesirable mass scenes. Watchable only once...

A somewhat brilliant one-liner can be found in H Vinoth and Ajith Kumar's third movie. Broadly speaking, this plot line attempts to spoof the bank robbery film while simultaneously turning the protagonist's moral compass on its head. There are clever ideas that are planted early to introduce the idea that a bank is fundamentally beneficial. 

Thunivu is a pure Ajith Kumar performance; he makes a big entrance, frequently shakes his leg, sends goons flying, and moonwalks through this cakewalk of a film. Ajith Kumar steals the show in Thunivu; he makes a big entrance, shakes his leg frequently, sends goons flying, and moonwalks through this cakewalk of a movie that doesn't ask too much of him. He also performs a moonwalk in a scene. Ajith portrays Dark Devil, a lone mercenary who works for hire. Dark Devil, Kanmani, and their gang double-cross Radha (Veera) and his gang when they seize control of a private bank in Chennai. They then make a deal with them. The Police Commissioner (Samuthirakani) assumes control of the situation outside the bank. A tale about a bank heist. 

As the fast-moving, high-octane first half continues, Vinoth introduces more characters to help round out his narrative. To name a few, there are a cowardly banker (John Kokken), a cunning journalist (Mohanan Sundaram), a timid constable (Mahanadi Shankar), and a sleazy inspector (Bagavathi Perumal). But there's never any mistake that Kumar is the star; his Black Devil powers the first 100 minutes of the film, which are filled with suspense and action.

Yet after that, the narrative makes a startling turn. When Vinoth blasts us with a barrage of revelations, many of which are delivered through some quite drawn-out flashbacks, the action is slightly dialled back. Dark Devil transforms from a merciless gangster to a roguish Robin Hood in a stunning but abrupt shift of pace. We'll soon be discussing mutual funds, credit card debt, and bank fraud. The bad guys are suddenly more than just gangsters. There are also news media, politicians, police, and bankers. Everyone in Vinoth's tale has filthy hands.
