I need to make sure the information is accurate. Let me confirm some points: the director is Sekhar Kammula, who made "Raghu Returns" and "Happy" before "Damarukam." The release year is 2012. The lead actors are Ravi Teja and Trisha. The supporting cast includes actors like Satya, Rao Ramesh, and others. The antagonist is played by Posani Krishna Murali, I think. The story involves the protagonist, a man in his 40s, facing a financial crisis due to loans taken for his son's education, leading to a battle for his dignity and financial stability.
