The characters in the movie are Sanjay Singhania,a chairman of Airvoice Company ( the largest cellphone company in their place ), who has an Anterograde Amnesia or shorterm memory loss after 15 mins..Kalpana, a helpful woman that Sanjay capture her heart when the first he saw her, one of the staff in the Advertising Agency.

Ghajini Dharmatma, the one who killed Kalpana and he is the reason why Sanjay loss his memory.
The movie entitled "Ghajini", there is a man who was a business and owned a huge building, he is a nice guy. When his bodyguard go to the Advertising Agency in order to talk with Kalpana to encouraged her maybe to work with Sanjay but Kalpana didn't forgive them. The boss of Kalpana and all the staff are thinking that Kalpana was the girlfriend of Sanjay but its not true, after that they gave all the support and care for Kalpana and they also call her "Madam". When Kalpana disguised to the people around her that she is the girlfriend of Sanjay Singhania, it was then in the news, so Sanjay was surprised when he saw the news because he even don't know that there's a woman who disguised to be his girlfriend. Sanjay wanted to go where Kalpana is. When he already in the place where Kalpana work, he amazed when he saw a woman helping the disabled children in order to cross in the village, maybe we can say that he love at first sight in that woman but he didn't know that the woman who captured his heart is Kalpana.
When they met each other Sanjay disguised that he is not Sanjay Singhania, rather he introduced himself as an ordinary person named Sachin, then Kalpana never doubt him. They already become friends and even more than friends.
July 1, 2006, the unexpected incident happened to the house of Kalpana, Sanjay had an Anterograde Amnesia or shorterm memory loss after 15 mins. because ot the tragedy happened when he help Kalpana in the hands of Ghajini. He had a memory loss because of the rod which strikes to his head and the cause of Kalpana's death. After that tragic, Sanjay experienced in his life of lossing his memory after 15 mins. after of lossing his memory he never knew what he did during that time. When Kalpana was killed by Ghajini she even don't know that Sanjay Singhania was the disguised person "Sachin". Sanjay found Ghajini who killed his girlfriend Kalpana by the help of his friend Sunita. They fought each other until he killed Ghajini.
In this movie, it was amazing and wonderful, its very touching story especially the character of Kalpana who's very helpful to the people who needed. We must do like kalpana eventhough she was killed in the said movie but she did her responsibility in order to help her fellowmen and she never regret to help others rather she was happy if there are some who need her help. As we lived in this world, we must face the consequences that no matter what comes in our lives because in our everyday living we don't even know if what will happen next, if it is good or bad.
