Gowri (Radhika) a village President's (Kanta Rao) daughter is a naughty girl in the village. A widowed school teacher (Chandramohan) lands in that village along with his son. Initially, she tries to trouble him, but after seeing his simplicity, good nature, and love towards his ex-wife (Rajyalakshmi), she falls in love with him.  She tries in vain to marry him by all means. Finally, she traps him to get married to her, but that brings distance between them, and he keeps away from her. How she wins his heart is the rest of the heart-touching story.

Geeta plays another important role as Chandramohan's colleague in the school, adding glamour to the film.

While Moodu Mullu was still in the theaters with a successful run, another producer dubbed the original into Telugu as Vaddante Pelli. That fared averagely at the box-office. The film was later remade in Hindi by R.C. Prakash of Sivashakti banner, with Rajesh Khanna and Sridevi as Master-ji, with K. Raghavendra Rao wielding the megaphone. The Hindi version was released on Aug. 22, 1989.
