📖 Plot & Thematic Premise (Based on Teaser / Press)

From the teaser and reports, Diesel mines the dark world of fuel smuggling and crude oil black market in Chennai. The plot revolves around the nexus between corrupt mafia, politicians, and insiders in the petroleum business.

Harish Kalyan’s character is caught in a conspiracy—he becomes a pawn in this illicit fuel trade. The teaser hints at strong visuals: pipelines, bombed rigs, trucks, underground deals, and gritty showdown scenes.

There are also an emotional undercurrent and romantic elements (Athulya Ravi’s character) intertwined with high stakes crime, setting up a balance between action and human conflict.
