Vaa Vaathiyaar revolves around Rameshwaran "Ramu", a man believed by his grandfather to be the spiritual successor of legendary Tamil actor and former Chief Minister M. G. Ramachandran (MGR), fondly called Vaathiyaar. Ramu is born on the very day MGR dies, which convinces his grandfather that the child carries the soul and responsibility of the iconic leader. From a young age, Ramu is raised on MGR's ideals of justice, compassion, discipline, and service to the common people. As Ramu grows up, the burden of this imposed legacy begins to weigh heavily on him. Despite his reluctance, he follows a path of authority and becomes a police officer, initially attempting to live up to the values instilled in him.
