The story of the film is about a teacher, who is unhappy with our education system, facing hurdles on his way when he tries to change the things forever. Dayalan (Samuthirakani) is a newly appointed teacher of a school in village. When he lands in the school, the situation raises a lot of questions on him and pushes him to bring in some changes.
Dayalan's decision for the change does not go well with other teachers and students. Like in every movie, there is someone in this movie too who completely opposes him. Singaperumal (Thambi Ramaiya), who is the Assistant Head Master wants to clip the former's wings and wages a battle against him. But Dayalan's good moves are slowly noticed by Pandian (Junior Balaiyah). Nonetheless, he continues to motivate children and stuns the school by changing the attitude of students, who were considered as arrogant-tough guys. In between, there is a love story between Pazhanimuthu (Yuvan) and Arivazhagi (Mahima). The remaining part should be seen on-screen.
Newcomer M Anbazhagan has an excellent script in hand. But it could appear to be too preachy after some time. His dialogues are wonderful and takes potshots at our education system. Nonetheless, he manages to give a good message with lot of entertainment. Samuthirakani has done an amazing job. His facial expressions at some serious scenes are treat to watch. Thambi Ramaiya, Yuvan and Mahima have done justice to their roles. Technically, Jeeva's cinematography is good and D Imman's 'Sahaayane...' track is the best song from the album.
Verdict: Saattai is good.
