Pratidwandi tells the story of Siddharta, an educated middle-class man caught up in the turmoil of social unrest. Corruption and unemployment are rampant, and Siddhartha cannot align himself with either his revolutionary activist brother or his career-oriented sister. The film is known for experimenting with techniques such as photo-negative flashbacks.
