I've been thinking about this for a while, so I thought if put it up to get some opinions.

The basic plot:

It would be centered around a group of people who have been time travelled (need to work that bit out still) back to Pompeii about three days before the eruption. I'm thinking it would be about how they dealt with being incapable of saving all of these people from the inevitable, and attempting to know them on a personal level while knowing that these people would almost certainly die.

It still need a bit of work. What do you think as a general idea, though?
