Pazhani was a naïve bank employee who had an unpleasant tendency to talk for hours and drove away every person within his orbit, while the jobless Seenu stole money from bar customers to drink alcohol.

The police find that the robbers' weapons were plastic replicas, and 5 crores were disappeared from the bank, but no clue was left.

A flashback reveals that Aadhi had roped two of his childhood friends Shankar (Shafi) and Hari (Nitish Veera), who were professional bank robbers.

Since the police are on their trail, they want to split and go to different towns by entrusting the job of carrying the entire money with a single man: Pazhani, who was not in the bank during the robbery.

In the meantime, the police inspector (Ajay) is charged to arrest the culprits, and he finds that five people were involved in this robbery.

With the help of another friend (Kadhal Dhandapani), Aadhi fakes his own death and deposits the money in Gayathri's bank account.

R. Yuvan (Prabhu Sekhar), brother of Telugu film choreographer cum director Amma Rajasekhar, made his directorial debut with Sindhanai Sei.
