It is an interesting tale woven around a cute kid named ‘Poori’ (Daisy Irani). Not knowing who his parents are, the kid has been looking high and low to get back to them. Seated in a park bench beside the hero (Gemini Ganesan), the kid asks his name and as soon as he replies, he proclaims that the hero is his father!
This creates complications in the hero’s life and ruins his plans of marrying his sweetheart (Savithri). The president of a hospital for the mentally ill with a not-so-mentally-strong daughter creates more problems for the hero.
After many interesting twists and turns, the truth emerges — the kid is the illegitimate child of a soldier (Mustafa) and the abandoned mother commits suicide, leaving the child behind. The hero and the heroine are so attracted to the child that they decide to adopt him.
