Katha Solla Poroms plot focuses mainly on four friends, Priya, Arun, Anita and Arjun who live in an orphanage. While living happily together as a family inside the orphanage, each one of them is yearning for parental care. This is clearly set up to be the premise of the story. While the narrative takes on a comic ride with Kaali Venkat, the four friends and their rival team of kids in a summer camp, a subplot wherein actors Naren and Vijayalakshmi search for their stolen baby also interweaves. A carefully crafted ending of the film leaves majority of the audience wiping their tears.
