One man army) or just Okka Magaadu is a 2008 Indian Telugu-language vigilante action film written, produced and directed by Y. V. S. Chowdary.

The film stars Nandamuri Balakrishna, Ashutosh Rana, Anushka Shetty, Simran and Nisha Kothari.

Meanwhile, the doctors, lawyers, and journalists terrifically vitiated society when a 101-year-old man, Okka Magadu, raises a missing in action against them.

Upon which, AK affirms it is impossible the man is old by his body language & strength and uncovers his young shade, i.e., Satyanarayana.

Simultaneously, Namboodriyar ruses to eliminate love birds and assaults them when they stab Baby / Sarada while hindering them.

Here lands Raghupati Raghava Rajaram / Okka Mogadu, Baby /Sarada's husband, a guerrilla & tall warrior whom she discerns and faints.

So, he reaches their village and claims Okka Magadu is a traitor when enraged Baby / Sarada reveals him as a great patriot who dedicated his life to the country.

Further, Okka Magadu retrieves the ill-gotten gains of CM from the Swiss bank and endows them to human welfare organizations.

On the spot, Okka Magadu exposes the diabolic shade of CM and produces the outlaws who are supposed to be slain by him before the judiciary.

Finally, the movie ends with showing Okka Magadu walking between the mountains by the side of the exploded aircraft.

The old aged looks of Balakrishna and Simran were designed by Eeswar, and the team went to the United States for 20 days to consult with make-up technicians.

Critic from Sify gave an unfavourable review, stating it to have "silly graphics, non-serious getups of Balakrishna, confused first half, monotonous screenplay and mediocre direction".
