Plot: Major Kathiravan (Vishal) is expelled from the Army because of his anger issues. To rejoin the force, he is ordered to get a NOC from Chennai-based psychologist Rathi Devi (Samantha). Just as Kathiravan gets closer to Rathi Devi and spends time with his family, he is tricked by a loan agent and loses Rs 10 lakh from his newly-opened bank account. While trying to get to the root of the theft he unearths a huge digital scam masterminded by Sathyamoorthy (Arjun) who goes by the alias of 'White Devil'.
Final Word: Irumbu Thirai feels like a lightweight version of the highly celebrated action thriller Thani Oruvan. It manages to entertain, engage and educate the viewer with its topical theme and interesting screenplay.
