How could a 68 year old woman look a 18 year old .That's the most unbelievable part .
Secondly after meeting Amulya his old wife ,it is incredulous to see them smooching and behaving like teens with the family and servants around .
What could have been a an interesting story spoilef by poor direction .The hero is a captain of the army and should be an intelligent person .After discovering the oddity ,he should have himself found out the reason for remaing young after 50 years instead of rushing to his so called family and start romancing his old wife .
