[2] As the title suggests, the story is about the efforts Kathirvel and his father, Egambaram, go through to solemnize the marriage of Lakshmi to whom they act as guardian and is daughter of a single mother Parvathi.

Trouble comes in the form of constant influx of people and circumstances ruining their attempts including that of the old lecherous Suruttu who wants to marry her; Maragatham who wants Lakshmi to marry her idiot son Gnanapalam; V.S Raghavan who first agrees and reneges for the marriage of Lakshmi with his son among others.

It is compounded by the fact that Parvathi's husband and Lakshmi's father, Ragunathan, is a fugitive from justice thereby not allowing Parvathi to reveal who or where her husband is not wanting to cause more trouble to the possibility of her daughter's marriage.
