I should focus more on summarizing the plot, characters, director's style, and themes of the movie. Sekhar Kammula is well-known for his social and family-oriented Telugu films. "Damarukam" might have a storyline where the protagonist goes through a journey of facing adversity, which is common in his genre. The title "Damarukam" could mean something related to a drum or a musical instrument, but in the movie, it might have a symbolic meaning tied to the main character's struggle.
