GURUKUL is one of India's top colleges headed by Narayan Shankar (Amitabh Bachchan). He is a man of staunch principles who does not like any changes in the way the college is run. He also opines that love brings only pain with it, so romance is strictly forbidden within the walls of GURUKUL. Enter Raj Aryan (Shahrukh Khan), the music teacher who not only believes in love but also induces three of his students to follow their heart and fall in love. Vicky (Uday Chopra) loves Ishika (Shamita Shetty) from girls' college nearby but Ishika hates him .
