Action comedy film ‘Quick Gun Murugun’, as obvious, is the story of an Indian cowboy. And unlike the actual cowboys of the US, here Murugun does not savour cows but is a cow saver! He believes vegetarianism is the need of the hour. He does not preach but rather fights people who are bent on turning the world into a completely non-vegetarian population.
The movie traces almost 25 years in the life of QUICK GUN MURUGUN who is bumped off by Rice Plate Reddy, the baddie. Rice Plate Reddy is forcefully turning all the pure vegetarian restaurants into non-veg ones and Murugun 'is not liking it' one bit. He polishes off his cronies 'Phatak se', with the subtle use of his guns and nimble hands. The bullets find its target after ricocheting off various objects. Rice Plate Reddy is angry and finishes off Murugun with a bullet to his heart. Yamraj descends to take his soul and all the way to heaven Murugun says, ''I want to go back''. At the registration counter 'Up There', he manages to convince the 'Heavenly Clerk' to send him back. He does come back, 25-years-later, but not in Kerala. Murugun is dropped at Gateway of India in Mumbai.
Rice Plate Reddy has by now set up a chain of McDosas all over the city of Mumbai and is also going international. Murugun's search for him leads to a volley of explosions and countless dead bodies. Yes, Murugun finishes off Rice Plate Reddy
