Muthyala Muggu (1975)

Raja Rao Bahadur (Kanta Rao) is the head of a wealthy and charitable family of landowners, and his rightful heir is his young son Sreedhar. At his son's request, Rao helps his college friend (Hari) with the costs of higher education abroad. Hari is grateful and invites Sreedhar to his sister Laxmi's (Sangeeta) wedding in the village. Due to unusual circumstances, Sreedhar ends up marrying Lakshmi. This enrages Mukkamala who is the Raja's brother-in-law, as he hhad entertained hopes of getting his daughter (Jaya Malini) married to Sreedhar.

What makes matters worse is that Laxmi wins over the royal household with her humility and good nature while Sreedhar falls in love with her innocence. She accidentally discovers a stash of the estate jewels in a well. Gurunatham and Mukkamala try to implicate the Priest. Laxmi suggests that since they do not know conclusively as to who stole jewels, they should spare the Priest.

Mukkamala, at the suggestion of the estate manager Joginatham (Allu Ramalingiah), then approaches Contractor (Rao Gopala Rao). Contractor agrees to break up the couple. But Contractor eyes the entire estate and its valuables and he entraps Mukkamala. He uses Kishtaiyya (Nutan Prasad) and creates suspicion in Sreedhar's mind with a sinister plan. Sreedhar falls prey to his doubts, comes to the conclusion that Laxmi is cheating on him and is only interested in his wealth.

He forces a pregnant Laxmi to leave with all the family jewels. Laxmi gives the jewels to Joginatham and decides to end her life. She is rescued by the Priest at whose house she gives birth to twins (a boy and a girl).

Meanwhile back at the estate, Sreedhar is depressed and loses interest in life and curses out Mukkamal when he proposes that Sreedhar should marry his daughter. Contractor then fixes up Kishtayya with Jaya Malini, and proceeds to squeeze Mukkamala out of his money. After that, he takes possession of several antiques that Joginatham was trying to sell.

All that's left is the Deity's Jewels. The Raja who is distraught with the unhappy atmosphere of the estate, decides to leave the Deity's Jewels in the temple, where they belong, and wanders around the villages.

He stumbles upon Laxmi's kids (his grandkids), discovers the truth and requests Laxmi to come back. Laxmi refuses to come back and declares that this does not work with recommendations and that Sreedhar himself has to accept his mistake and come to her and ask her to come back. Raja Rao Bahadur, with the help of the kids and Sreedhar's friend, hatches a plan to set things right with Sreedhar and beat the Contractor at his own game. Can the youngsters defeat their enemy, dissolve the rift between their parents, and reunite their whole family in happiness and harmony?
