There is a man on the road, full of burns and is in a great deal of pain. People crowd around him.
CID Lab: Niyati checks on him, and she is wearing a protective gear, mask, and gloves and notifies ACP Prad and the team that the man is suffering from a deadly virus and that she doesn't know the name of the virus yet.
Daya and Abhijeet are in the bureau. Daya is preparing coffee for Abhi. Just then, Daya receives a call from his friend Rahul. Rahul tells Daya that he has something important to tell him about a CD. He has asked Daya to meet him at a street.
Rahul is in his car and soon his girlfriend Minakshi (Shama Sikander) comes and tells him that she came here to meet him and that he shouldn't cancel their plans. Rahul is hesitating. He tells Minakshi that he has to tell Daya, his friend something and then they can go out for lunch.
Street: Daya and Abhi call up Rahul again and ask him where he is. Rahul says that "they" are just close by. Daya and Abhi look for him. Just then, Rahul gets killed by a bunch of people (gang). Daya and Abhi come over and see why there is a huge crowd. Daya sees his friend and Rahul tells him that he hid his CD in a store and that if they don't find it, then everyone will die. Rahul then dies. Daya cries and laments. Abhijeet takes pictures of the crime scene. He asks the people if they saw anyone with Rahul. They say no they haven't.
Daya tells Abhijeet that there must have been a person w/ Rahul since he used the word "they" over the telephone. Daya says that he isn't married, and so Abhi says that he must have been with his girlfriend.
CID Lab: Niyati tells Prad that the name of the "deadly virus" is called Nimakshi. This virus had been stolen from the World Bank some years ago by some Dr. (forgot his name, but let's assume his name is D'Souza) as he was doing a research on it.
Daya and Abhijeet wonder about the possible hiding spot for the CD. Daya says that Rahul must have hidden the CD at a near by DVD/CD store, since that it why he called them in that area. So, they find a nearby CD Store. Abhijeet shows the pic of Rahul to the store owner and asks him if he saw Rahul. The store owner says yes and that he went to this side of the store.
Daya and Abhijeet search the whole store and checks every DVD Box and finally they find a CD. They ask the store owner whether he has ever seen that CD. Store owner says no.
@ Dr. Shroff's place: Minakshi is crying and says that she can't believe Rahul is dead. Dr. Shroff says that Rahul found out about their plans and so had to finish him off. He tells Minakshi to concentrate on their mission.
CID Bureau: They play the CD on the recorder and hear Rahul's conversation w/ someone. Just then in the background, they hear something about a bomb and the phrase, "571E1115". Prad writes those letters/numbers on the board and thinks what it might mean. Everyone is thinking. Dr. Niyati comes in and asks them what it means. Just then Prad says that 571 E means it is a bus 571 which is an express. Abhijeet says that 1115 means that it is the 11:15 am bus. Fredricks says that they only have a little time.
They search all the buses and Abhijeet finally finds the bus and finds the box w/ the virus inside installed in a bomb w/ his metal detector. He only has 3:00 mins to go until it explodes.
Daya catches on w/ the bus and both Abhi and Daya go to a lonely spot. Just then, they receive a call and Prad tells them that Niyati told him that the virus could only be destroyed in high temp. Therefore, w/out losing any time, both Daya and Abhijeet run and Daya shoots on the jeep's tank and it explodes.
CID Special Lab (w/ protective shielding): Both Daya and Abhi are being checked by Niyati to see whether they have contracted the virus. Thankfully, they are alright and are safe and sound.
Prad finds out Dr. D'Souza's address and w/ the team he reaches the Dr.'s house. The doctor meanwhile in his wheelchair is writing the name Nimakshi on the wall many times. They arrest Dr. Shroff. Dr. Shroff says that noone can stop him from spreading the deadly virus.
Meanwhile Minakshi scolds the guy who had put the box containing the bomb on the bus. She tells him that her plan has failed because of him. She also says that people had wrongly accused her dad, Dr. Shroff for stealing the virus, but now she doesn't care, since they tarnished their reputation, she will kill all the people w/ the virus. She puts on the jacket with the bomb.
CID reaches Minakshi's place and there is a face-off between her and the officers. But she manages to run away and comes to a party and holds a woman captive. She tells the CID that if they come near her, she will shoot her and the bomb will explode as well. But Abhijeet comes behind her and they both fall into the swimming pool. The bomb explodes.
prad asks Fredricks to go inside and look for Abhijeet. Fredricks finds him and puts him to the ground. Abhijeet says that he is fine and smiles.
