Inner Ghosts

HELEN is a neuroscience researcher trying to develop a revolutionary therapy to treat degenerative brain diseases like Alzheimer's. To prove her theories, she needs to run cognitive tests on ghosts: beings who apparently can act and remember without the need of a physical brain - suggesting that unresponsive patients whose brains are too damaged to function can be accessed, somehow, through their living souls. After the death of her mentor, Helen finds an apartment inhabited by benign ghosts who agree to be tested. The problem is Helen renounced her gift 15 years ago after the loss of her daughter when she made a vow never to contact the other side again. Things start to change when an artist called ELSA begs Helen for some spiritual training hoping to get rid of a demon who has been haunting her for many years.
