Abhinav, an astrophysicist living in Kolkata India is on a mission to search for possibilities whether time travel is possible or not. He stays alone in a flat and most of the time he is busy playing with his tools and learning new techniques to build up a technology based on Stephen Hawking's theory of space and time. He makes a model that he believes can serve the purpose of time travel but on the other hand he fails everyday but he never gives up and records every activity on a camcorder . One day after his falure, he received a mail from his old friend Kaustav to sit for a coffee chat, as he rarely meets people he agrees. Abhinav and Kaustav both were having a good time in the coffee shop when suddenly one word which was said by Kaustav clicked Abhinav's mind, he quickly went back home and did a bit research on that topic and he was amazed. He stared changing few things in his model and few derivatives. He started the process again but again failure, he took a deep breath and lit up a smoke and went up to film himself about the failure when suddenly he heard a noise behind him, he turned and saw that object which came back but was not the same.
