‘Maari 2’ starts from where ‘Maari’ ended. Maari (Dhanush) still rules his locality with the help of his best friend Kalai (Kreshna). One thing he hates in his career is drug business, but the rival gang wants him to join with them so they can sneak it without any problem.

But, Maari strongly opposes the plan. Meantime, there is Beeja also known as Thanatos (Tovino Thomas) who has vengeance against Maari for killing his brother. When Beeja escapes from jail, he works with Maari’s rivals and plans a cunning scheme to separate Maari from Kalai.

Beeja’s idea works well and he nearly kills Ma... ler o resto.
