Avishek Karthik and Daniel Annie Pope are petty thieves. They soon get fed up with their poor life and about the fact how everyone treat them both as fools. So they decide to kidnap a rich kid and start a new life with the ransom money. That's when they meet Samapath Raj, well off businessman and his daughter - Baby Sathanya.

After a few attempts they successfully kidnap Sathanya, call up Sampath and threaten him to give them money in return for his daughter's life. Sampath out of fear readily agrees to give them the ransom. In this situation Dhanshika in her cop uniform, meets and casually engages both Avishek and Daniel in a conversation. 

Soon after that, she finds out that they both have kidnapped a girl, and tries to save Sathanya by herself. The rest of the plot revolves around how Dhanshika save the girl from her kidnappers, what's her background story, and will Avishak and Daniel really go to any extend to get the ransom. 

Avishek Karthik has given an impressive performance with his debut film. He is able to emote different kinds of expressions and has all the credentials to be a commercial hero. Dhanshika pulls of her tough cop role with ease and has done an impactful performance. 

Daniel Annie Pope's humour works really well. His one liners are really something to look out for. Sampath Raj has pulled of his negative shaded role well. John Vijay as always has nailed his character. Kali Venkat plays a pivotal role and has yet again delivered a convincing performance.

S Kalyan has done a decent job at the directorial department. Though the story starts of in a pretty confusing way, it all connects together once we understand the characters well. The humour is the main backbone for the film's success. However, the director could have paid more attention to the screenplay as it is little draggy at parts. 

Both Deepan B and R Pavan's tunes could have been more effective. Relatively the background scores are much better. Jemin Jom Ayyaneth's cinematography skills come to the for and he has shot well. So, Vijay Velukutty editing. 

In short, Kathadi, is decent.
