On one occasion, Raja comes to the rescue of an older man and becomes seriously injured in the process. When he is healed, he comes to know that the older man is a smuggler. What is Raja's true connection with the smuggler? Will he ever come into contact with his father? Can Raja resolve all these problems and happily marry Rani?
