Sunder (Mehmood) works in a hotel owned by Ram Swarup (David Abraham) as a waiter. He is a very funny, uneducated man, with a suitably funny face, opposite to his name. Radha (Leena Chandavarkar) is the daughter of Ram Swarup. She often comes to the hotel, and Sunder happens to meet her and amuse her with funny jokes. One day, in a casual remark, she says,"I like your innocence". He does not understand the word 'innocence', and thinks that she likes him. He also likes her, but is afraid to tell her, as he works in her father's hotel.
Then, he seeks help from his friend, Amar (Biswajeet). He helps him get work in film industry. And in no time, Sunder emerges as leading comic actor. But in this duration, Amar, ignorant about his friend's love, and Radha fall in love. When he knows that Sunder's love is Radha, he asks Radha, who says that she never loved Sunder. Amar stops Sunder multiple times from expressing his feelings to Radha, thinking that the truth will break down Sunder.
During his stardom days, he once performs at a charity show for orphan children. He gets emotional seeing the children, and decides to stay a day longer, and in the process, misses his father's death ceremony at his home. Her mother asks him to be with her in her last moments. And he promises to.
One day, during an interview to the All India Radio, he says that he likes to have his old dress of the waiter in front of him, so that it could remind him of what he was earlier, and he does not develop any pride. And in the same interview, he says that he is going to marry someone he loves. Amar and Radha listen to this on the radio. Knowing that Sunder will come to express his love to her, Radha urges Amar to tell him the truth, but he says, he is unable to do so. Sunder comes, and Radha tells her the truth. Heartbroken, Sunder wishes for his friend, and Radha.
Then, one day, he goes for the shooting of the climax of a film, whose date of release has come very near. The producer says to his guard that nobody, in any circumstance could disturb them. And back home, his mother falls down the stairs. She is rushed to the hospital. She wants to see her son, so, a man is sent to call him, but the guard does not allow him in. Instead, he himself goes to get some good medication. Sunder, after finishing the work, comes to know about the accident, and rushes away. But he finds her dead. He repents being a celebrity.
Amar and Radha marry. At that ceremony, Sunder comes in his old dress, of a waiter. He says, he will no longer work in films, as that life is unreal. He will meet his mother now onwards, by helping poor and orphan children.Mehmood ... Sunder
