Bujji (Prabhas) and Chitti (Trisha Krishnan) are inseparable childhood friends. One day while they are playing, Chitti gets angry as her sandcastle was destroyed by Bujji. She scolds him and tells him to go away from her and never meet her again. When he pleads her, she asks him to prove his sincerity by staying away from her for 12 years and promises to marry him if he does so. Though devastated, Bujji reluctantly agrees to stay away from her and moves to Chennai to keep a distance. Meanwhile, Chitti's family moves to Hyderabad, cutting all ties from Bujji's family.
