Raja Babu is the story of orphan Raja (Govinda), a rural man alien to urban sophistication. He is accompanied by his ``sidekick`` Nandu (Shakti Kapoor) who is just as whole-heartedly accepted by the family as Raja himself. Raja`s life changes when he sees Madhubala`s (Karishma Kapoor) photo at a photo booth, a place he often visits. He instantly falls in love with her and after an incident, at which Madhubala is thrown away by his smart personality and impressive talk, she also begins to reciprocate his feelings. But, there lie hurdles in their path of love. Will they be able to make it past them?
