Sigma Movie Plot 

Sigma follows a radio host played by Sundeep Kishan whose life changes after he becomes involved in a large criminal operation. The trailer reveals that the story revolves around a reported ₹500-crore racket involving drugs and gambling. After being betrayed and losing what matters to him, the protagonist decides to fight back. He eventually plans a major heist with the help of his friends.

Faria Abdullah plays Sam, an RJ who is connected to the protagonist. Their relationship forms the romantic side of the story, while Sampath Raj plays Reddy, a key figure on the opposing side. The film also brings in humour and family emotions alongside the crime and heist storyline. The trailer specifically hints at the bond between a mother and her son, giving the story a personal element beyond the central robbery.

The complete details of the heist and its outcome have not been revealed, so the trailer establishes the premise without giving away the entire story.
