The Feast (2023)

It's just another [excruciating] meal for Vienna - until an offer to conquer her greatest fear in 'three simple steps' arrives. Desperate for freedom from her fear of eating, Vienna takes the offer up - only to realize she bit off far more than she can chew... As Vienna is taken through these three escalating steps to conquer her fear, she also discovers just how resilient she is, ultimately fighting anorexia back in the most defiant way possible: by reclaiming her autonomy in eating.
