After rescuing Neena (Nargis), a wealthy young woman, Dilip (Dilip Kumar) falls head over heels for her. As time passes, Dilip becomes more involved in Neena's life, ingratiating himself with her good friend (Cuckoo) but not with her father (Murad), who disapproves of Neena and Dilip's interactions. While Neena remains oblivious to Dilip's true affections, several events transpire to disrupt their current arrangement -- one of which is the return of Rajan (Raj Kapoor), Neena's fiancé.
