Kundan Shankar (Dhanush) is the only son of Tamil Hindu Brahmin parents settled in Varanasi. Since his childhood, Kundan has had a strong and obsessive one-sided love for Zoya (Sonam Kapoor), a Muslim girl residing in the other neighborhood, whom he had seen doing namaaz in his teacher’s house while he went to collect chanda or donation for Hindu festival, Dussehra. He always attempts to flirt or be around Zoya but gets slapped several times in the process.
