"Mental Rust" is a hard-hitting social drama that targets the deep-rooted, rusted mindset prevailing in government offices. It narrates the story of public servants who, over time, start believing themselves to be masters rather than servants of the people whose taxes pay for their positions. The story follows a young RTI activist, Arjun, who sets out not for revenge but to reform a decaying system that wronged his family. Through protests, legal battles, and public awareness drives, Arjun challenges those government employees who misuse their power and neglect their duties.
