Pompeii, the lost Roman city buried by the eruption of Vesuvius in 79 AD, has long been a source of fascination to archaeologists.  Its sister city Herculaneum, buried in the same eruption but to a much greater depth, reveals an even more complete picture of Roman life.  While much of Pompeii has been explored, new archeological digs in Herculaneum are revealing new insights into the events of that day. The program follows scientists as they try to piece together the horrific day and discover a surprisingly different scene from that described at Pompeii.
