He may be homeless but Ben is making the best of things. He has a tent, he has access to food, and even has a couple friends.
However, when a mysterious stranger appears, offering food and safety to him and his friend Connor, his instincts tell him not to trust it, instincts that are proven right when Connor is nowhere to be found the next day.
Someone or something has been culling the vagrant population and nobody seems to notice or care, so when he sees the stranger again, Ben will have to follow him to the source, even if his pursuit of truth brings him all the way down to a Hell he may never escape.
Because The Worm Mother has been waiting for a very long time, and has no intention of letting him go.
