Siva aka S.K (Sivakarthikeyan) is a theatre actor whose only aim is to become a superstar like Rajinikanth. However, his lack of acting out romantic scenes hinders his path to the dream, and is even rejected by director K. S. Ravikumar during the audition for his new film ''Avvai Shanmugi 2''. He comes across Kavya (Keerthy Suresh), who is a doctor, and instantly falls in love with her. He goes to her house to propose his love, only to find out that she is engaged to a Pune-based doctor Vishwanathan alias Vishwa (Anson Paul). Siva, though distraught, decides to woo Kavya anyway and somehow break her engagement with Vishwa. He disguises himself as a nurse, going by the name of "Remo" (short for "Regina Motwani", a combination of the names of actresses Regina Cassandra and Hansika Motwani, and takes up a job in the same hospital where Kavya works.
