I watched Exodus Decoded last evening. The program argues that the Biblical story of the Jewish exodus from Egypt was an actual historical event along with the accompanying plagues, parting of the Red Sea, and so on. This link contains a counter argument. More information and many links are found here.

The film moves the date of the Exodus to about 1500 B.C., about 300 years after it has traditionally been dated. The reason for this change is to align the Exodus with a volcanic eruption on the Greek island of Santorini -- an eruption that offers an explanation of the plagues.

The program connected a lot of dots, so to speak. As always, evidence is subject to interpretation.
