Murugan is a typical vegetarian cowboy who made himself into Quick Gun Murugan. The cowboy has to do something good for the world so he believes that vegetarianism is the need of the hour.[3]
Quick Gun Murugun enters into a battle that spans time and space, from a small south Indian village to Heaven and then finally to cosmopolitan Mumbai across 25 years. He is torn between Mango Dolly who loves him secretly and his first love Locket Lover and his loyalty is put to the test.
Mango Dolly gets hit by a bullet and while dying, she expresses her love to Murugun. Realising that he too loves Mango Dolly, he tells her that he loves her and she can "stay with him". Finally, Quick Gun Murugun is able to succeed in his mission by defeating Rice Plate Reddy.
