Five strangers awake in an underground dungeon and discover that they've been kidnapped as part of a terrible experiment. A sadistic scientist wants to answer a simple question: What are they willing to do to survive after weeks without food? As the days go by and their hunger becomes unbearable, the captives struggle to retain their humanity. Lori Heuring, Joe Egender and Lea Kohl star in this dark examination of mankind's lowest instincts.
Good movie, not a storyline you see everyday either. It was sort like Saw, only no escape, only continuing to live on. It was however pretty creepy to see what some of them did.
