The movie starts with a series of incidents of a happy life of mom and a daughter back in 1934. At present in 2016 Dr. Krishnakanth Acharya / Krish (Siddharth), a successful brain surgeon, and his wife Lakshmi (Andrea Jeremiah) live peacefully in their beautiful house under the mountains in Rosina Valley. Their perfect life together is now disturbed after a family moves into the house next door where the mother and the daughter lived in 1934. Jennifer D'Costa / Jenny (Anisha Angelina Victor) is a troubled teenager and neighbour of Krish and Lakshmi. Losing her mother at the young age, she has turned out to be a rebel. While she doesn't despise her caring stepmother, she never misses a chance to throw tantrums at her either. But, she loves her halfsister Sarah. One day soon after relocating to the new house Jenny comes to meet Laxmi with Sarah and make friends with her. She is instantly attracted to Krish's charm and makes an attempt to come closer to him. That night while exploring the house Krish saw Jenny jumping into the well and saves her. Jennifer's rebellious nature makes her do things like smoking for example. During one such time when she sneaks out of the house for a smoke, she picks up some belongings of a dead person. Jenny starts to act weird soon her family moves in the house. So, Jenny's grandfather contact a nomad but Paul refuses to take any help from him. So, Jenny's father Paul D'Costa (Atul Kulkarni) with Krish's recommendation contacts Dr Prasad (Suresh). After Jenny tells her that there is someone who is telling her to leave the house and a few strange incidents happened to her the doctor concludes she has developed Paranoia with visual and auditory hallucinations. They have also arranged a hypnotherapy session where Jenny tells her it is Li-Jing and not her who has went to the hills. And a series of paranormal incidents abound that affects the lives of the people around her. Jennifer's new house is haunted by three ancient Chinese spirits, and one of them is a man and he is bloodthirsty while the other two spirits are the mom and the daughter who helps the family to get out of the house without trouble. The mother daughter duo continues to warn the people to leave the house but they don't leave. Paul calls the Pastor to perform exorcism on Jenny but the session leaves Pastor in Coma with Krish and Paul heavily injured. Later on, when it is believed to be everything is fine, Laxmi becomes pregnant and the maid in Paul's house disappeared. Paul agrees to call the Nomad witnessing this and he revealed there is a spirit of mother and daughter who are asking them to leave. He also discovered the bodies where they were burried. Krish accompanies Dr Prasad when he decides to visit a lady from the neighbor village to know what has happened to Paul's house 80 years ago. The lady revealed to them how the man of house Lu Wei has killed her own daughter to get a baby boy. The major twist comes up in the end of the story where DR Prasad is killed as he understood the truth that not only Jenny is possessed by the woman's spirit but Lu-Wei has possessed Krish to fulfil his unsuccessful work 80 years back. Aval is not just a conventional humans vs devil narration. It has an angle of good spirits vs bad spirits and how the living suffer as they are jammed between this supernatural tug-of-war.
