Vikram Rai Bahadur is the only son of Mrs. Sharda, and sole heir to a vast business and estate. While vacationing with his artiste friend, Gogi, he meets a beautiful girl named Sunita and falls head over heels in love with her. He proposes marriage to her, and she accepts. They get married in a quiet temple ceremony and vow never to part with each other.
Shortly thereafter their vehicle meets with an accident. While Gogi sustains minor injuries, Vikram is badly hurt and hospitalized, and Sunita is severely disfigured. Dr. Sahni and Dr. Mehra befriend Sunita and restore her disfigurement by plastic surgery.
She quickly recovers, and cannot wait to give the good news to Vikram. Then she finds out that Vikram has given up on her, and is engaged to another beautiful, but wealthy young woman named Rita. Vikram is unable to recognize Sunita nor is interested in knowing her. Sunita decides to change her name to Kusum Mehra, and begins life anew. Will Vikram and Kusum's paths cross in the future, and if so, will they be able to remember their vows?
