A professor, Rajendra Prasad adapts a dog (Tommy) and Tommy becomes a member of the family in a short time. An untoward incident changes the family's life upside down. Tommy has a major role to perform since then. The way the dog has been trained to perform in the film is superb. All the scenes featuring the dog and Rajendra Prasad are quite emotional and have been executed well.

The film opens when Madhumati or "Madhu" (Bhoomika Chawla) and Siddartha Roy or "Siddhu" (Pawan Kalyan) are born. Madhu's family is based in Konaseema in Andhra Pradesh and Sidhu's family is from Kolkota (he has a Telugu father and Bengali mother). As babies, Madhu and Siddhu meet in a shopping complex. Madhu and her father love each other dearly. Madhu's father wants her to marry so that the son-in-law can stay with them and his daughter will not leave her.
