The film begins in 2001 with a woman, Kanyakumari, being sent to prison for murder. The action then cuts to the present where Shakthi alias Pattas is leading a happy life that involves some small-time thievery and playful retaliation against Sadhana, a snooty neighbour. The latter makes him steal from her workplace, a mixed martial arts academy run by Nilan. But Pattas realises that he has a history with Nilan, when he meets Kanyakumari, his long-last mother. She wants him to avenge the murder of his father, Thiraviyam and bring glory to Adimurai, the ancient martial arts form that he practised.—Santhosh
