The new Tamil film Ka Ka Ka Po is directed by P.S.Bijay and stars Kesavarajan and Sakshi Agarwal in the lead roles. After completing his studies, hero Kesavarajan stays at Chennai with his friend Aadhavan and is in search of a job. He has to face many hardships as his lucky stars do not favour him and even his family has to undergo lot of problems.

At the same time, heroine Sakshi Agarwal seems to achieve whatever she wishes. Knowing her lucky state, business man Subbu Panchu wants to marry her at any cost. On the other hand, the hero, who happens to meet Sakshi by chance, starts liking her.

Subbu Panchu throws a party to seven of his close friends and the heroine's family before the marriage. Though not invited, Kesavarajan attends the party along with his friend. When liquor is served to the guests, Sakshi also consumes the drink. While coming down after the party, the heroine happens to collide with the hero and everything goes the other way round after that incident. The second part of the movie shows what happens after that and the happy ending.

Hero Kesavarajan, who is no more, looks apt to the innocent character and has done his part well. The whole movie revolves around heroine Sakshi Agarwal and she has done justice to the given part. Actors Subbu Panchu, Powerstar Srinivasan, Robot Shankar, Karunas, Madan Bob, Mayilsami, Sandi and Aadhavan are given equal importance and they can be appreciated for the perfect portrayal. M.S.Baskar, who comes as a wizard gives guarantee for hilarious comedies.

Director Vijay has taken a different plot that consists of astrology and signs (which are to be considered superstitious) and has added humour to attract the audience. Songs and the BGMs are enjoyable with the composition of Dina, Hamara and P.C.Sivam. Iqbal's cinematography looks equal to the big budget films and proves his capacity.
