Having a painful past and shunned by the rest of his family he lives with his father who supports him wholeheartedly. One day Premachandran notices Kanmani, a poor ill-treated servant girl. When Kanmani decides to end her life Premachandran dissuades her and takes her into his care. To give the slip to her former abusers and to avoid suspicion, Kanmani dresses up as a boy and soon joins Premachandran's team of carpenters. There are repercussions when the girl starts to fall in love with him.
