Lovable goon Munna falls for a morning radio host by the name of Jahnvi, who also runs an elders' home which an unscrupulous builder seeks to attain. In order to gain Jahnvi’s attention, he cheats his way to winning a Mahatma Gandhi radio quiz. When Jahnvi consequently expresses interest in Munna, he and his best friend Circuit attempt to keep up the facade.
