Synopsis: Scientific Magic

Five people and a cashier are drawn into a fantasy world whilst waiting in line at the local supermarket. They are informed of their Destiny and how they must Destroy The Ancient And Ultimate Evil... preferably without Katryn, the physicist/cashier who came by mistake.

So the five travel on foot whilst the sixth, an old drunken man, disappears, presumably into a bar (or a cardboard box. He could have mistaken it for home), despite the fact that there is perfectly good magically powered cars one can drive, because It Was Written That Way.
