In the film, Anand alias Bruce Lee, a martial artist, wears a superhero costume in order to impress his girlfriend Shakthi, but Anand gets framed for his friend Viji's death and sets out to prove his innocence by becoming a real superhero called Mugamoodi.

[4] Anand alias Bruce Lee, a college graduate, lives in Chennai and studies martial arts with a group of similarly jobless friends as he hates the idea of 9-5 jobs.

Anand, in an attempt to recruit new students to pay tuition fees and save their school, gets involved in a brawl and falls for Shakthi, the daughter of DCP Gaurav.

Anand wears a borrowed superhero costume and introduce himself as Mugamoodi to Shakthi, where he tries to impress the children with his skills and accidentally ends up in the middle of a police chase.

Anand (masked himself as Mugamoodi) saves them by defeating the gang and takes Gaurav's file containing the latest findings of the case, including the fingerprint match, as he wants to avenge Viji's death.

The gang seizes a port and kidnaps 30 children, along with three adults including Shakthi, as hostages to blackmail the cops.

With the help of his grandfather and friends that had him sneaked into the port, Anand kills some key members of the gang.
