Vasu (Jiiva) is a house broker who sells houses by using tricks with his friend Sooranam (Soori (actor)). He has a pet dog named Scooby. Vasu and his mother Parvathy (Raadhika) are living in her brother's (Ilavarasu) house for rent. Vasu and his parents had lived in houses for rent throughout their lives. After Vasu's father's (Uday Mahesh) death, he took a vow of buying a bungalow on the outskirts. After some years, Vasu buys the bungalow and enters the house with his whole family.
