In the meantime, the leader of a political party, M. S. Bhaskar entrusts Vivek Prasanna with a major responsibility which other party members do not accept easily. Vivek Prasanna's appointment for the top job irks many including party member Venkatesan, who hatches a plan to oust him. He comes to know Vivek Prasanna is fond of watching himself in videos featuring women and decides to steal his mobile phone under the hope of leaking the footage and humiliating him. He then instructs his henchmen to get hold of that mobile phone, who then entrust Karthik with the task.
Karthik then gets involved in an accident and his left hand is affected by Alien Hand Syndrome. This condition leads to his left hand performing actions by itself beyond his control and leads to many problems for him. He manages to however steal Vivek Prasanna's mobile phone. What happens next to Karthik, what all problems he has to ensue as a result of his new condition and what happens to his relationship with Anjali Rao forms the rest of the plot of Peechankai.
Karthik has shouldered the entire film and doesn't show any signs of inexperience despite the film being his debut. His actions when his left hand goes out of balance leading to many awkward situations are hilarious to watch. His expressions in the beginning of the film when he's going full swing with his skills and then facing the consequences of the condition are all enjoyable. Anjali Rao looks lovely and has performed her role to a tee. M. S. Bhaskar has yet again chosen a different role and the same can be said about Vivek Prasanna as well as Venkatesan, who have played their parts well.
Director Ashok has attempted to make a film that explores an unexplored theme and his casting for the characters compliment the story. Although there are a few boring scenes here and there, we feel satisfied towards the end for having watched a rather good film. Balamurali Balu's songs are all highly enjoyable. The introduction song "Smooth" written by Sukumar Ganesan is a delight to listen as well as watch. He's also scored high marks in the background score department. Cinematographer Gautham Rajendran has shot the film in such a manner that we don't get an impression of watching a low budget venture.
In short, Peechankai is strong.
