King Karma Dev (Pradeep Kumar) gives a lot of importance to physical beauty. He can't stand being around dark women. He has a harem of queens, all of them fair and beautiful. However, he does not have a son from any of them. His mother, Rajmata( Durga Khote) requests the Mahamantri Munjal Mehta (David) to find him another wife, who would give the dynasty its heir. The fact that Karma Dev often dreams of marrying an unknown beautiful woman he had once seen in a Somnath temple complicates matters further. Mrinalla (Vyjanthimala) is the princess of Karnataka, who also dreams of marrying a king she had once seen in a Somnath temple as a young girl. In her quest to find him, she rejects many kings and princes. Although Mrinalla is a very fair and beautiful woman, her complexion is extremely sensitive to exposure to sunlight. In fact, prolonged exposure to sunlight makes her complexion turn darker - it takes quite some time for her complexion to return to its normal color. Munjal Mehta happens to see Mrinalla during one of his travels in searching for a beautiful woman for Karma Dev. He carries back a painting of Mrinalla for the king. He also secretively arranges for the painter Vichitram (Om Prakash) to take Karma Dev's painting for Mrinalla to view. Mrinalla is happy to finally find the man of her dreams. However, she is heartbroken to learn that the King has refused to marry anyone. She runs away from the palace to convince Karma Dev on her own. She roams around in the harsh sunlight for many days, which turns her complexion very dark. Meanwhile, Karma Dev is being allured by a dancing girl Kamanjala (Shashi Kala). Unknown to the King, Kamanjala is being helped by Uday Mantri (Jeevan) in getting her the man of her dreams. Soon after, Munjal Mehta shows Mrinalla's painting to Karma Dev, who agrees to marry her. Mrinalla is brought back to the palace for the marriage. However, on the day of the marriage, the King finds out she is dark and refuses to marry her. Rajmata brings Mrinalla (now rechristened Minal) to her palace and vows to make her son accept her. Due to Munjal Mehta's planning, Karma Dev is forced to marry the dark Minal. However, he refuses to solemnize the marriage. Uday mantri meanwhile plays his cards and tricks the king into believing that Mrinalla's painting was actually of the dancer Kamanjala. He also lies to Kamanjala that the king has fallen for her after seeing her original painting. Karma Dev calls Kamanjala to his place one night. Munjal Mehta and Minal go to Kamanjala's place and manage to convince her to let Minal go as Kamanjala. Karma Dev is very happy to see Kamajala and gives in to her charms. The news of the king and the dancer's illicit relationship soon becomes common knowledge. The king is asked to purify himself by embracing a red-hot statue of the dancer. Rajmata and Munjal Mehta stop this ritual and make Karma Dev realize his follies of running behind only physical beauty. They also chide him for treating the dark Mrinalla unfairly. Karma Dev regrets his actions and asks his mother for forgiveness. He is then told that the women he assumed to be Kamanajala, was actually his own wife Minal. He is delighted to learn this and accepts her as his Patrani. Soon, the couple is blessed with a son.
