Ruhi Singh soon gets them out on bail and Natty after befriending with few of the inmates in jail gets involved in car theft jobs. He lands a Rs. 10 crore payment in his first theft and Munishkanth joins him in the next few days. In the meantime, Sharath Lohitashwa, a Madurai-based don orders Natty to get him 10 luxury cars. While in Madurai to get the cars, he comes across the car that was stolen from the company he first worked in and puts an effort to get it too. Bongu then revolves around whether Natty retrieves the car and hands it over to its owner and if he manages to get the job done for Sharath Lohitashwa.
Post Sathuranga Vettai and Enkitta Mothathey, Natty has once again chosen a role with substance and has delivered a commendable performance. Although her role isn't as big as it could have been, Ruhi Singh fulfills her part in a satisfying manner. Arjunan has kept up his consistency in his comedy antics along with Munishkanth, who once again adds yet another feather to his hat. Sharath Lohitashwa comes again as a dangerous villain and he lives up to his role. Despite appearing in only few scenes, Atul Kulkarni has come up with a clean act.
Director Taj has made a film with an interesting script and screenplay at its foundation. His casting choices as well as extracting work from his actors and the dialogues written deserves praise. Mahesh Muthuswamy's cinematography skills come to the fore and he has shot the film befittingly. Srikanth Deva's songs are enjoyable, but he elevates himself as a composer in the background score department.
In short, Bongu is the King Kong of Tamil heist films.
