One day tragedy strikes as his father the only earning member dies in an accident while crossing an unmanned railway gate and the young boy now has to look after his mother and two sisters. Mahesh, along with hundreds of others, works at the Senthil Murugan Stores run by the big Annachi where 50 to 60 sales boys and girls work in pitiable conditions from early in the morning to late at night, without any rest.
