Shanthi Nivasa, commonly known as no.73 Shanthi Nivasa, is a large house with a number of selfish, quarrelsome, and peculiar residents, with the exception of Radha. The situation is so bad that one servant barely remains for a month. When Raghu enters the house as a cook, things begin to change as he imparts morals and values in each of them, which clears the smokescreen of misunderstandings that separate the relatives. Meanwhile, a lookout notice is given for a criminal who has escaped from prison and is skilled in stealing from houses after working as a servant, cook, music teacher, and dance teacher by gaining the trust of the respective family members. Although Raghu continues to impresses everyone with his vocabulary and multiple skills in dance, Sanskrit, and music, he secretly has eyes on the box of jewels and gold. Who is he and what are his intentions?
