The story is about Teera , the son of a hard-working, single mother.

Teera is just an ordinary teenage kid who loves to have fun in life. He is not a diligent student and has never really done anything to make his Mother proud. But she loves him and works hard to give him every opportunity in life.

As the University Entrance examination nears, Teera reflects on all the sacrifices his mother makes and begins to feel guilty about his lack of effort.

Within the limited time frame, he starts to pay attention to his studies, works hard and is finally able to make his mother proud!

The 86,400 minutes he devoted to his studies is worth the one moment when he sees the look on his mother’s face…a moment they will both remember and cherish forever!
