The story is based on Indian historical events during the 16th century. It narrates the victory of Viswanatha Nayak on his father to express his devotion towards Srikrishnadevaraya. Viswanatha Nayak (Krishna) is the son of Nagama Nayak (Sivaji Ganesan), a successful General of Srikrishnadevaraya (Krishnam Raju) of the Vijayanagara Empire. Chola King Veerasekhara Chola invades the Madurai Kingdom and deposes the Pandya King Chandrasekhara Pandyan who was under the protection of Srikrishnadevaraya. Due to this, an enraged Srikrishnadevaraya sends Nagama Nayak to aid Chandrasekhara Pandyan. Nagama Nayak suppresses Veerasekhara Chola and takes Madurai, but then suddenly he calls off his allegiance and declining to help Chandrasekhara Pandyan usurps the throne. So, Viswanatha Nayak volunteers to face his father in the battlefield.
