Kaithi is the story of a Terrible Night of coincidences which led to a battle between Police and Drug Cartel and an ex-convict Dilli got stuck between them.

A mediocre script turned into an action packed thriller. The entire story focuses on just one night. When massive consignment of drugs gets siezed by Inspector Bejoy,Anbu & his drug cartel begins a war against police department in order to regain their consignment. Dilli an ex-convict is released after 10 years & was misunderstood as a criminal by a police officer,gets cuffed and later on as the clock moves forward coincidently gets stuck in a war between drug cartel & police department. Now he is assigned by Inspector Bejoy to rescue police officers and must take them to hospital with the help of a truck. On the other hand an another part of story also goes on simultaneously at comissioner office where a new constable & 5 college students gets stuck coincidently.

The film has Karthi as Dilli an ex-convict eager to meet his daughter almost after 10 years,Narain as inspector Bejoy was nicely portrayed & Arjun Das as Anbu ,the Drug Cartel leader was a great choice.

Director Lokesh Kanagaraj has made a fine action thriller with an emotional subplot. The cinematography is kept dark as entire movie is set in the night. Aniruddh has composed a solid & hard rock background score which makes action scenes more entertaining. Combination of Hollywood style background with a Desi character was a great creative idea. Its background score is it's plus point.

Overall movie is fine & serves as a mediocre dum biryani (Lokesh Fan will understand)
