Shakthi secretly learns that Anu really loves and takes care of Megha. He married Anuradha aka Anu ( Pranitha Subhash), who is a teacher of his daughter Megha's ( Yuvina Parthavi) school, just for Megha's wish. Shakthi was a police officer in Quebec City, Canada. While Massu is furious with Shakthi for having made him a double murderer, Kamal meets Massu and starts telling him Shakthi's past: Massu is Shakthi's son. Meanwhile, Shakthi manages to use Massu to kill another person, Madhivadhanan aka Madhi ( Charles Vinoth), an MLA and associate of Anthony. This incident moves Massu, and he fulfills the wish of every ghost. Her wish fulfilled, Padma attains salvation. As a sort of seeking forgiveness, he guides her son, takes care of him, and gets his eyes operated upon. Massu is frustrated to learn that he is accidentally responsible for Padma's death. He first fulfills the wish of the ghost of a woman named Padma ( Rethika Srinivas) which is to see her son, who is blind. He starts fulfilling the wishes of all the ghosts. The ghosts go with Shakthi, but Jettu manages to convince Massu, and he agrees to fulfill the wishes of the ghosts. Just then, Shakthi arrives as the ghosts have called him. Massu yells at them and orders them to go out. Meanwhile, the ghosts start striking against Massu as they assume that he would cheat them. Corrupt ACP Vikram Lakshman ( Parthiban) takes charge to investigate the case and finds out that Massu is somehow involved in the murder. He sabotages the plan and tricks Massu into running over Anthony Xavier ( Sharath Lohitashwa), a hawala broker. However, he wants to use Massu for his own needs. Shakthi initially seems to help Massu to pull off a large heist. One day, Massu meets a ghost called Shakthivel ( Suriya), a Sri Lankan Tamil and lookalike of Massu. Meanwhile, Manini, who thought Massu was working in a finance company, gets to know about the fake exorcisms and leaves him in a heist.

Massu forms a group of loitering ghosts to earn money by performing fake exorcisms and extorting money from scared, rich people, while promising the ghosts that he would fulfill their last wishes in return. Jettu had died in the accident and is now a ghost, too. While trying to escape after a heist gone wrong, Massu and Jettu meet with a car accident, post which Massu starts seeing dead people, with whom he can communicate.

Massu meets Manini ( Nayantara), a nurse, and they subsequently fall in love. The story then shifts to Masilamani aka Massu ( Suriya) and his friend Jet Li aka Jettu ( Premgi Amaren), who are small-time con artists. The film starts with the murder of a former Police Commissioner, Shanmuga Sundaram ( Subbu Panchu), by an escaped prisoner named Kamal Ekambaram ( Riyaz Khan).
