After returning from overseas, heiress Rita is stressed out and needs to go someplace to unwind. She chooses Kashmir and, upon arrival, rents a houseboat from the owner, Raja. After a few misunderstandings, they are attracted to each other and soon fall in love. This romance is not looked upon favorably by Raj Bahadur Chunilal, Rita's dad, as he would prefer his daughter marry a suitor he has chosen for her: Kishore. Rita dislikes Kishore and will only marry Raja; the wily Raj Bahadur devises a plan that will let him keep the cake and eat it too.
