Final-year mechanical engineering students, Romario, Riyas, Yoodas, and Athmaram, think their lives are miserable since there is not one single girl in their class. Much to their joy, a girl called Riya joins their class and soon becomes friends with the boys. Termed as 'Mech Rani' of the college, all the boys from the mechanical department begin to flirt with her, leading to comical situations.

The story starts with the inauguration of the first-ever Mechanical batch in an engineering campus. The batch consists of boys only. Later in the second year of the department, a girl joins and becomes the only girl to be a part of their batch. As the story evolves, the girl grabs all their love and attention and becomes the QUEEN of the batch.
