The Placebo Effect

Adam gathers his friends around the fire...
to tell a story:

Seth Lynch has an unfortunate accident, which leaves him, let's just say... changed. And when more tragedy strikes, it becomes clear... he can no longer distinguish his nightmares from reality.

Seths sister Arielle, makes a discovery in the house they recently moved into. When mixed with Seth's mentally ill mind, they bring a storm of terror to the Lynch house... one there is no remedy for.

Adam says it's just a story...
