Kasi picks up a phone that belongs to businessman Karthik on an impulse. What he doesn't realize is that the phone had compromising videos of the latter, which soon leads to trouble for both the young men.
The one question that we want to ask after walking out of
is — why can't Tamil film directors make a thriller film without including pointless songs and annoying comedy tracks? This film, an official remake of the Malayalam film
(which was inspired from the Korean thriller
), is a cat-and-mouse thriller between two men who are neither good nor bad, just victims of circumstances. Initially, we think of the rich Karthik (Prasanna) as a playboy (he even is planning to dump his co-worker Monika and marrying Pavithra, the girl his parents have in mind for him) and our sympathies are all with Kasi (Vemal), who works in a departmental store. But, halfway through, we start empathizing with Karthik while Kasi becomes a person who is toying with him. These slightly grey characters, who are the film's protagonists, make Pulivaal mildly refreshing.
The film opens with a nicely-edited montage (TE Kishore is the editor) of their daily lives — Karthik selects from a bunch of newspapers, while Kasi takes a peek at the day's news at the tea shop; Karthik takes a shower in his luxurious bathroom while Kasi has to wait in queue at the public toilet and fetch water to take a bath; and so on. And, Karthik, not surprisingly, owns an iPhone while Kasi uses a phone that is bound together by a rubber band.
The mobile phone is what sets the plot in motion as Karthik's iPhone ends up in the possession of Kasi. And, it is important for Karthik to retrieve the phone because it holds a video of him having sex with his employee Monika. Kasi, who has taken the phone on an impulse, is guilty and decides to return it, but, before he can do so he realizes that he can use Karthik to get back at people who are mean to him — like the hostile Valliappan (an irritating Thambi Ramaiah), his store manager. He also doesn't know how to use the phone but, can Karthik track him down before someone learns of the phone's content?
This is definitely a juicy plot and in Vemal and Prasanna, Marimuthu has actors who look their parts. And, yet, he slips because he cannot nail the tone required for this subject. He devotes a rather large amount of time on trivial elements that hamper the story's flow — like Valliappan's romance with a co-worker (with Ilaiyaraaja's songs turning into BGMs), Soori's comedy (which is a compilation of many SMS jokes), and out-of-place songs (that are unimaginatively picturized). Every time something tense happens, the actions cuts to some of these mundane scenes and so, we never really get involved with the story. It is only in the final 30 minutes that the film shows some signs of sticking true to its genre but, by then, it is too late.
