Rachana (Shraddha Srinath), an intern, with The Indian Express, a daily newspaper, is working on an article on the incidents at a Bangalore flyover. She also has a crush on the crime reporter Aditya, whose help she seeks for research material on accidents on the flyover. She finds that each day some motorists move the concrete blocks that partition the road just to take a quick U-turn and avoid the traffic. They don’t move them back and the blocks are left to lie randomly on the road leading to many accidents. A homeless man sitting on the flyover notes down the vehicle numbers of commuters who violate the rule to take the U-turn and gives the list to Rachana. She obtains the details of the culprits using her contact in the traffic department, with the intention of confronting them for their “short-cut” and writing an article for the paper. Her attempt to meet the first person on the list goes in vain.
Later the same day, the police take her into custody and accuse her of killing the same person she wanted to meet. She is shocked and tells her side of the story. Though the senior police officer rejects it, sub-inspector Nayak finds it believable and does some investigation. It is revealed that all the persons Rachana has on her list have committed suicide. They also noticed that they have committed suicide the same day they took the wrong “u-turn”. Rachana and Nayak find another number has been noted by the homeless man which is to be delivered to Rachana the next day. The duo trace the address and try to rescue the man, a lawyer, who has taken the u-turn on the same day. As nothing seems suspicious, both leave only to encounter the very death of the lawyer whom they came to rescue.
Later Rachana tries to confront the homeless man for the injuries in the fly-over. Meanwhile, she sees two young men violate the U-Turn and reports it to Nayak. Nayak locks them up in an old Police lock-up to save them. But they start fighting and eventually die under the nose of the police.
With no way of finding the real cause of the death of the culprits, Rachana herself takes the wrong u-turn and waits for something to happen. The one who has been killing the culprits is a woman named Maya, because she and her daughter Aarna died in an accident due to the concrete roadblocks that were moved by the culprits in order to make way for their u-turn. Using her supernatural powers, Maya tries to kill Rachana as well. But Rachana promises to find the person who was responsible for Maya’s death. Maya agrees. Rachana, with the help of Nayak, tries to find the person who moved the blocks on the day of Maya’s accident. They find out the phone number and address of the guy who moved the block. Rachana writes this on a balloon and leaves it on the flyover for Maya to find. She then invites her boyfriend Aditya for dinner.
During dinner she tries to call the number she found out earlier. It turns out to be Aditya’s work mobile number. Devastated she confronts Aditya and informs him that due to his negligence a mother and daughter lost their lives. Aditya says it was not him who made the U-turn. He merely exchanged his bike with his friend. In the final twist, it is revealed that the guy who moved the block was Maya’s own husband. Maya’s ghost is waiting in Aditya’s house to kill him when Maya’s husband whom Rachna has informed about the events turns up and explains to Maya that it was because of him that they lost their lives. He then tries to commit suicide by jumping from the balcony. Maya’s ghost saves him and tells him that his punishment is to suffer in this world without his wife and daughter.
