Hellbender

In a house on the top of a hill in the woods, the teenager Izzy lives with her mother and has no contact with civilization since she has a mysterious disease. She is home-schooled by her mother and plays drums in the trash-rock Hellbender band with her mother. They are vegan and her mother occasionally goes to the town to buy art materials. One day, a hiker is lost in the woods and asks Izzy how to reach the road. He says that he is the uncle of her teenage neighbor Amber. However, mother asks Izzy to go home and walks with the man and out of the blue makes him disappear. A few months later, Izzy meets Amber at home, and she invites Izzy to swim in the swimming pool with her. She also invites Izzy to return on the next day since she will have her friends with her. Izzy is challenged to drink tequila with a worm inside. Soon Izzy hallucinates and her mother explains who Izzy and she are and why they are vegan.
