Prem (Salman Khan) is a Love Guru who solves the love issues of his clients.
He meets Bhaskar Diwakar Chaudhary (Govinda) who comes to Prem for help in his love life. Bhaskar loves his boss Priya Jaisingh (Katrina Kaif) but is unable to express his love to her as she is the daughter of a wealthy businessman. Prem initially refuses to help Bhaskar and goes to Phuket, Thailand. Bhaskar follows him there and convinces him to help him.
After coming back from Thailand, Prem meets Naina (Lara Dutta), a photo journalist who was running from some gangsters led by Chhota Don (Rajpal Yadav), who mimicks Shahrukh Khan in Don. Prem saves her and falls in love with her.
Meanwhile he starts teaching Bhaskar how to impress Priya. But Bhaskar uses his own simplicity and non-sense acts to impress Priya. Priya finally falls in love with Bhaskar but does not disclose it to him.
Prem comes to know from Bhaskar that Priya is getting married to someone according to her father's will. They both come to Priya's wedding ceremony with Naina, and Priya's father is convinced by Bhaskar's acts. Priya now gets ready to marry Bhaskar.
Prem thinks that Bhaskar may commit suicide without Priya and goes to her to tell her what really happened. Priya realizes that all the things she liked about Bhaskar are what Prem wanted Bhaskar to hide from her and Priya is ready to take Bhaskar back.
Prem makes up with Naina by making her hear the truth about him not helping Neil, and they get back together. On both couple's honeymoon night Bhaskar again asks Prem for help but this time they both get mingled with their respective wives.
