Por Thozhil is about a newly recruited DSP trainee Prakash (Ashok Selvan) teaming up with seasoned officer SP Lokanathan (Sarath Kumar) over a serial killing case. Lokanathan is least interested in mentoring the rookie and the rookie decides to prove himself by helping Lokanathan solve the case. A series of murders happen with the perpetrator leaving no clue and randomly choosing the victims. How the duo find the real killer when they have literally no motive to work with forms the story.

Por Thozhil solely works for it's writing which gives no space to deviate from it's limited set of characters and their sub plots. Kudos to the director for keeping proceedings tense and especially the first half simply stands out with that terrific interval block. The subtle treatment does the trick and having seasoned actors like Sarath Babu and Sarath Kumar is a casting masterstroke. The second half though doesn't match the first half which had set the bar too high, it still delivers with the rightly placed twists despite choosing the predictable narrative.

With strong performances and a tight narrative, Por Thozhil is another worthy entry into the investigative thriller genre and is worth watching. Definitely recommended.
