'Aivarattam' is a movie based on football game conducted in Sivagangai district and this story focusses on five members of the team. Jayaprakash is a big shot in Sivagangai district. He owns a football team  which is consists of two divisions such as junior and senior teams. His sons Niranjan Jayaprakash leads the senior team while the younger son Dushyanth Jayaprakash is the captain to the junior team.

Though they are brothers they always fight with each other. One day these two teams compete with each other. The teams enter the ground with the pledge that they will not enter the ground again if they lose the match. The junior team loses the match.

On the other side Jayaprakash's brother Amruthkalam gets married to a woman belonging to a different caste and is abandoned from the family. Jayaprakash takes the football team owned by his brother. So Amruthkalam trains the junior team and take them till the finals in a championship game that is being conducted in their place. Who wins the finals and what happens to the family feuds is narrated in the rest of the story.

Niranjan and Dushyanth have played their part well. Heroine Nithya Shetty has less chances to perform since the movie concentrates mainly on the sports and the family problems.

Jayaprakash excels as usual with his experienced acting. Debutants Amruthkalam and C.K.Senthilkumar have done their parts well.  Saminath's music and the cinematography of Ravindranath Guru are not upto the mark.
