I ask you, where is the intersection between heaven and hell, of good and evil?

It's a packed train. Humans crammed in like sardines.
No air to breathe, no space to move, the stuffy heat, muffled breathes, and strange smells.
When a man and woman meet under such conditions, it's natural to gave in to natural desires.
That's when the train becomes a hunting ground...

Welcome to the molester's paradise that is a train packed to 300% capacity.
