A 28 years old nutritionist that after 5 years of enduring severe depression, she decided that the world was not made for her. She sold her house, quit her job, and decided to live life in a different way, as a nomad of some sorts; just her and her car. Not even a week after this adult tantrum, she read somewhere about an experiment which got her attention and her absolute will to participate. Having no regards for her life anymore, she didn't even hesitate to join without a care in the world. 

She was told she could leave at any time, but she never left. Her past life is a blurr now. Did she ever have a life before? Has this always been her life? Is this a simulation or real life? However, this is her reality now. Survival.
