Vizag city is plagued by a mafia gang, headed by the most powerful mafia don Satya (Raghuvaran). Satya, who is physically disabled, is the mastermind while his son Seshu (Rahul Dev) implements those strategies with his muscle. Together they make a terrific combination. Ganesh (Nagarjuna) enters Vizag and settles in an apartment. After noticing the menace by Satya's henchmen, Ganesh calls up Seshu and warns him about four dates of that month - 15th, 20th, 25th and 1st (next month). He would harm and cause damage to them for 3 dates and finally would put an end to the life of Seshu on the 1st. (15,20,25 and 1 numbers displayed in 1st trailer of MASS have significance in story) The rest of the film is all about how Nagarjuna implements his strategies to scare the gang and the reason behind Nagarjuna's mission of coming to Vizag.
