Sailom, a poor and studious student, works several odd jobs to help his elder brother in his efforts to keep them afloat. One day, Sailom has a run-in with school bully Kanghan and becomes his primary target after refusing to be cowed. However, fate plays its hand when Sailom is offered a sum of money too great to refuse and he takes on the role of Kanghan's private tutor. Despite their difference, the two develop an irrefutable connection.
