Output: In the year 2065, a scientist Arya invents a time machine. To prove its capability, he sends it back in time to 2015, programming it to return within forty seconds. However, the machine does not return. The time machine is seen by three people in 2015 — Elango Vishnu, a budding entrepreneur whose ideas are rejected by all and who is struggling to maintain his relationship with his rich girlfriend Anu Miya, who is embarrassed at the fact that Elango is unemployed; Elangos best friend Pulivetti Arumugam Karunakaran, a fake astrologer; and an inventor Giridhara Parthasarathy T. M. Karthik, who makes a living by repairing home appliances. The three of them are involved in an accident and witness the time machine while recovering from the shock. While Parthasarathy decides to keep the time machine for himself, he suffers an electric shock and ends up in a coma, prompting Elango and Arumugam to steal the time machine from Parthasarathys shop. The duo use the time machine to make Arumugams astrology practice extremely successful by going back in time and finding things lost by people under the guise of astrology. Elango further uses the machine to impress Anus industrialist father Rajarathinam Jayaprakash by going to the future, obtaining the stock market results and successfully predicting them in front of Rajarathinam and his companys board of directors. Rajarathinam soon approves the marriage of Anu with Elango. Things go smoothly until Elango and Arumugam inadvertently thwart an encounter to kill Kuzhandaivelu P. Ravi Shankar, a dreaded gangster and extortionist who is targeting Rajarathinam, during one of their trips to the past to find yet another item of one of Arumugams clients. In the present day, Kuzhandaivelu is plotting to kill Rajarathinam for his role in planning the encounter and also Elango and Arumugam for unknowingly attacking him in a parking lot. Elango and Anus marriage is postponed indefinitely as a result. Elango and Arumugam go back to the past to fix their mistake, but Kuzhandaivelu accidentally shoots the time machine while fighting a police officer during the encounter, damaging it. The duo find Parthasarathy, who has woken up from his coma but doesnt remember them, and ask him to fix the time machine. While Parthasarathy manages to fix the time machine, due to a lack of specific parts which have not yet been developed, it can only take the user to a specific time in the past when Kuzhandaivelu damaged the time machine and also as the date cannot be changed, the user cannot return to the future. Therefore, the duo decide not to use it. Later, Kuzhandaivelu spots Elango, Arumugam and Anu at a mall and pursues them. He opens fire during the chase, killing Anu. To ensure that Anu remains alive, Elango decides to use the time machine to return to the past and kill Kuzhandaivelu, even though he cannot return. But Kuzhandaivelu spots the duo and while fighting them, all three of them fall into the time machine and go to the past. In the past, Kuzhandaivelu destroys the time machine, but Elango manages to kill Kuzhandaivelu. Then, Elango and Arumugam stop themselves from finding the time machine by thwarting the accident involving them and Parthasarathy. The next morning, Elango wakes up in a bed, remembering only the events of the previous night. He soon finds out, to his surprise, that he is in a marriage hall and that he is getting married to Anu on that day. He does not remember, to Anus bewilderment, any of the events which had occurred in the past two months as a result of his usage of the time machine during that period. He finds out that, without finding the time machine, he got a job and managed to impress Rajarathinam with one of his business ideas, leading to his marriage with Anu. Arumugam, who also doesnt remember anything over the past two months, is happily married. Elango and Arumugam soon find out that Kuzhandaivelu had died two months ago. They also run into Parthasarathy, who does not recognise them as they had never met. Since the time machine was never seen, it returned to 2065, making it a success.
