Out of Line

Little San woke up in the middle of an factory. Soon he discovered that he isn't alone. Far from it. There are several other kids, that look exactly like him! 

At the distance, sound of machines are heard. They became closer, and closer, louder and louder... All of the sudden, out of nowhere, several hooks appear and start picking up everyone! What is this place? Can San and his new found brothers escape this devilish environment?
