Chaos

Aman is a medical student at National Medical College. One day, in the middle of the class he gets a call from an unknown number. He doesn't attend the call. Later, he gets a message from the same number that says "Call me". He asks permission from the professor and goes to the washroom. The caller tells that his name is Bryan and he has kidnapped his brother Ram. In order to return Ram, he asks him to bring the ring finger of the right hand of his associate who had been shot dead by a rival, Anthony's gang that day. His body is taken by the police for post mortem to the College-Hospital where Aman studies. The kidnapper warns Aman of the dire consequences if he informs the police. Aman stays in his college hostel while Ram stays in his patent's house. However, their parents had to go out of town for a family function and couldn't take Ram along with them as he had his school exams. 

Aman goes to the mortuary during the forensic medicine class. He sneaks into the room where Bryan's associate's corpse is kept and finds the ring finger missing. He then realizes that it is a prosthetic finger that has already been kept separately by the forensic team. He takes the finger and calls the kidnapper who tells him to wait for further instructions. 

Aman goes to his hostel room and finds that an expensive drug is stuffed inside the finger. Anthony sends henchmen to break in into the mortuary and steal the drugs. But, he is shocked when the henchmen inform him the prosthetic finger is missing. Anthony had already struck a deal with drug cartel leader Arthur for money in exchange for the drugs. Failure to deliver the drugs would form a huge rift between them. 

Aman gets a call from Bryan who tells him to come to an abandoned warehouse alone. Meanwhile, Aman's roommate Rishab finds out the drug stuffed inside the prosthetic finger. He misinterprets Aman to be using it and drains it in the washbasin out of anger. Rishab then overhears Aman talking to someone about drugs and think that he is a drug dealer. He calls the police station and informs this Inspector Prem. Aman panics when he finds the drug missing. He asks about it to Rishab but Rishab acts like he doesn't know anything. Aman then replaces the drug with chalk powder and stuffs it inside the prosthetic finger.

 Meanwhile, Ram overhears Bryan's conversation that he is going to kill both Aman and Ram after getting the drugs. Fearing for his life, he tries to escape. He asks the henchmen to untie him to go to the washroom. In the washroom, he breaks open the window and manages to escape. He runs as far as he could and sees a vehicle. He goes near the car and asks the person for mobile to contact his family. However, he unintentionally reveals to that person that he was kidnapped by Bryan's gang. That man is a member of Anthony's gang. He takes him to Anthony who forces him to reveal the reason behind Ram's kidnapping. Ram tells them that Aarav was going to deliver the drug to Bryan's gang. 

Bryan's gang desperately tries to find Ram but all in vain. However, they send two henchmen to spy on both the hostel and Aman's home and confirm that Ram hasn't returned back to his family nor contacted them. Bryan tells one of his henchmen to get the drugs from Aman from the hostel but he backs out as a police car was approaching. Inspector Prem is coming to the hostel as Rishab called. The henchmen tell Bryan that police came to Aman's hostel. But, Bryan believed that Aman would never call the police as he knew Aman still thinks Ram is captive under them. 

Rishab tries to stall Aman till Inspector Prem arrives. But, Aman goes out telling that it's urgent. Aman plans on delivering the prosthetic finger and runs from the warehouse with Ram as soon as possible. He gets a call from Bryan. Bryan tells Aman to deliver the drugs to his henchmen who are waiting near his hostel and cuts the call before Aman could enquire about his brother. Aman decides to give the drugs to the henchmen as he has no other option. Just before delivering the drugs, Anthony's gang attacks him and takes the prosthetic finger. This happens in front of Bryan's henchmen. Aman chases them frantically. Bryan is informed about this through the henchmen. Bryan tells the henchmen to follow Aman.

Inspector Prem comes to Aman's house and enquires about Rishab. Rishab tells that he had drained the drugs and Aman left the house. Inspector Prem scolds Rishab for both wiping out the evidence and letting go of the culprit. He believes that Aman has fled the city. He calls the control room and tracks Aman's phone. Anthony's gang goes to the rendezvous point where they have struck a deal with a drug cartel led by Arthur. Anthony gives the drug to Arthur who immediately recognizes it as fake. He believes that Anthony has betrayed him. Aman reaches the place and so does Bryan's gang and a three-way fight ensues between Bryan's gang, Anthony's gang, and Arthur's cartel which is ultimately subdued by Inspector Prem and his backup who had arrived there just in time. The Inspector arrests all the people except Aman. Police find Ram in Anthony's hideout and free him. Aman happily returns home with Ram.
