In Aayirathil Oruvan it is Kalabhavan Mani in the lead role. Mani unlike his emotionally overdone roles in Vinayan films is doing a well-defined and controlled character of a middle class young man Aravindan. The story reflects the plights of middle class families in the present Kerala society.

Aravindan has two sisters and the elder one is not married. This naturally disturbs him, as he is the only bread earner of the family. In between his personal and family problems he gets married.
