Prem Yog is a 1994 Indian Hindi-language romantic comedy film starring Rishi Kapoor and Madhoo.
The story deals with Maharaj Chhatrapal Singh (Shammi Kapoor) and his wife the Maharani, who are delighted when they become proud parents of a son - the heir to the throne of Ramgarh.
Their delight is short-lived when the Palace Astrologer predicts that Chhatrapal will be the last of the Maharajas for Ramgarh, and no throne is destined for his son, Raju (Rishi Kapoor).
Perturbed at this news, Chhatrapal decides to protect Raju from the world and makes him lead a secluded life within the four walls of the palace and its surrounding grounds.
He meets with and falls in love with a dancer and singer, Anita Sethi (Madhoo), who is the daughter of a wealthy man.
