Ziddi Dil Maane Na

Colonel Pushpendra Batra, founder of Parakram SAF Academy, comes out of retirement and starts a civil training program due to increased terrorist activities. He promises the minister that if he fails in his mission he will return all his medals to the ministry. He chooses his three best special agents to carry out this program: Special Agent Karan Shergill, a very strict and brave commando; Special Agent Sanjana Dubey, a rough and tough commando and Special Agent Faizuddin Siddiqui, a cheerful guy who is committed to his country. The academy is in Deolali.

Dr. Monami Mahajan is kind-hearted and helpful by nature and has decided to join the training against her father's wishes. Her best friend is Siddharth Ganju, and they are quite close. She sees Karan, who is trying to stop Bala, a thief who has stolen his wallet, and picks a fight with him. The recruits arrive and Karan asks them to trek in the forest to enter the academy, thinking that the weak recruits will quit. All the recruits enter the academy by the allotted time but Monami, who almost reaches the gate, goes back to help Koel, another recruit, and is 30 seconds late. Monami convinces Colonel Batra that she is fit for the academy and she too is admitted. She earns the name "Monami Tsunami" from the trainers and "Rani Sahiba" from Karan for her privilege, while she calls Karan "Khadoos Shergill".

Sid arrives at the academy and claims that she is to be his fiancée. She denies it but as Sanjana beats him, she accepts it. Sid claims to have a rare heart disease and Mrs. Batra throws an engagement party for Sid and Monami.
