Omkara or Omi [Ajay Devgan] is a gifted chieftain who heads a gang of outlaws which include the crafty Langda Tyagi [Saif Ali Khan] and the dynamic Kesu [Vivek Oberoi] amongst his chief cohorts. The story begins when Omi appoints Kesu and not Langda as his chief lieutenant. Langda''s pride is slighted and raging with envy he hatches a plot to falsely implicate Omi''s beautiful lover Dolly [Kareena Kapoor] in a love affair with Omi''s �favorite lieutenant� Kesu. With the unwitting aid of Indu [Konkana Sen Sharma] Langda''s wife and the willing help of Raju a fellow grouch Langda''s plan takes shape and results in horrific tragedy.
