Kuch Khatti Kuch Meethi Sunil Shetty,Kajol Double Role,Rishi Kapoor Raj Khanna (Rishi Kapoor) is a wealthy businessman who lives with his wife Archana (Rati Agnihotri), stepsister Devyani (Mita Vasisht), her spouse (Pramod Moutho), and her son Teddy (Mayur), in a mansion. Raj and Archana's lives are marred by marital discord, until they separate. Shortly before separating, Archana gives birth to identical twins: one of these is taken by Devyani and handed to Raj without Archana's knowledge. This infant becomes an embittered young woman sentimentally named Sweety (Kajol), and Raj becomes a helpless alcoholic. Archana has moved to London with the other daughter, Tina (Kajol). In contrast to Sweety's ferocity, Tina is meek, compassionate, sympathetic, and demure. Each year, Archana buys two identical presents, gives one to Tina on her birthday, and locks the other into a closet to symbolize giving to Sweety, whom she believes is dead.
