The Panagarh Institute of Engineering & Management welcomes the new batch of First-Year Engineering students. Among them is Aratrika Roy, a young and enthusiastic engineering student who has joined the residential hostel with others. She enjoys her newly found independence until a student goes missing on campus and a professor dies. Things quickly turn dark when she witnesses a questionable person entering the girl's hostel late at night and seeing the same person being followed by a suspicious shadow. After midnight the same shadow is seen again inside the girl's hostel trying to steal something, prompting the police to investigate. As an avid reader of detective novels, Aratrika tries to solve the mysteries plaguing her college and discovers something she never should have. She learns the hard way that appearances can be deceptive. Do the disappearances of two more students in the Engineering College affect the hostel and college life of hundreds of students? Can she hunt down a perilous killer alone within the campus? Is she able to find the truth, or will she perish trying?
