Ganesh, an orphan, lives with his best friend Aadi and is in love with Anjali, a college student and the daughter of Satya, a disabled crime boss in Vizag. Anjali restricts from falling for Ganesh as it would land him in danger, but she finally accepts his feelings. Anjali tells Ganesh that they should marry immediately before her brothers Seshu and Satya tries to separate them. While on their way to the temple where Anjali is waiting, Ganesh finds that he forgot to bring his late mother's photo and goes back to bring it with him. Aadi reaches the temple for Ganesh and Anjali's wedding, but finds Seshu forcing her to return with him. Seshu kills Aadi when he tries to stop him from taking Anjali away. Ganesh gets enraged at Aadi's death, where moves into Vizag under a new identity as Mass and begins to eradicate Satya and Seshu's crime syndicate. In a final confrontation Ganesh fights with Seshu and defeats him, where he reunites with Anjali and leaves the city. Satya kills Seshu out of disgrace and commits suicide, thus avenging Aadi's death.
Music composed by Devi Sri Prasad and was released on ADITYA Music Company. The audio was released in an entertaining function held at Taramati Baradari (Golkonda).
The film opened with 191 prints.
A critic from Sify wrote that "Mass, at best packs in sufficient thrills to add up to a fairly engrossing entertainer, which keeps the popcorn popping". Jeevi of Idlebrain.com wrote that "There are no boring moments in this 2.45 hour film though. You should watch Mass on the big screen to enjoy the charming Nag in his new avatar".
