[3] Dayalan (Samuthirakani) is a newly appointed teacher of a government school in Vanthaarangudi village near Thiruvannamalai city.

Dayalan's decision for the change does not go well with the other teachers and students, but his good moves were slowly noticed by Pandian (Junior Balaiah).

Students study well and they top their district, and the movie ends with Dayalan giving the responsibility of HM to Singaperumal, who reforms and apologizes to him.

[6] M. Suganth from The Times of India gave it 4 out of 5 and claimed that Saattai was a "commercial potboiler dressed up as arty fare".

The reviewer further wrote: "Anbazhagan's intentions are quite commendable [...] but the sad thing is that he goes about this task with less subtlety and more sermonizing, with the result that the scenes where he wishes to make a point come across as totally preachy".

[8] Behindwoods's reviewer gave it 2 out of 5 and noted: "The preachy dialogues in the film are what students listen to in real life.

[9] In September 2015, Samuthirakani chose to postpone the production of his Kitna, after the lead actress Dhansika got an offer to appear in Pa. Ranjith's Kabali (2016).

Samuthirakani also revealed that the film's plot line had been taken from a real-life incident, which happened when choosing a school for his son.
