LUV DHOKHA (Echcharikkai) is a story about David (Kishore) and Thomas (a good debut by Vivek Rajagopal). Thomas? father, an alcoholic, kills his wife when she refuses to give him money. On learning about his sister?s death, David kills his brother-in-law in front of Thomas. While David cradles his dead sister, Thomas immediately chooses to go to his father and hugs him. You see where the loyalties lie. David asks Thomas to bear his crime ? the sentence would be shorter as Thomas is a kid and David would be there to provide for Thomas. We see Thomas agree and you suspect David of emotional manipulation. During interrogation, the police slap Thomas and David instinctively turns away. We realise that the equation is more complex. They kidnap Shwetha (Varalakshmi Sarathkumar) and her father Perumal seeks retd DIG Natraj?s (Sathayraj) help.
