Your flavor should be represented above for a more in depth analysis. I, for one, prefer the Chabad site.
The nutshell take:
As told in the Bible, after many decades of slavery to the Egyptian pharaohs, during which time the Israelites were subjected to backbreaking labor and unbearable horrors, G‑d saw the people’s distress and sent Moses to Pharaoh with a message: “Send forth My people, so that they may serve Me.” But despite numerous warnings, Pharaoh refused to heed G‑d’s command. G‑d then sent upon Egypt ten devastating plagues, afflicting them and destroying everything from their livestock to their crops.
At the stroke of midnight of 15 Nissan in the year 2448 from creation (1313 BCE), G‑d visited the last of the ten plagues on the Egyptians, killing all their firstborn. While doing so, G‑d spared the children of Israel, “passing over” their homes—hence the name of the holiday. Pharaoh’s resistance was broken, and he virtually chased his former slaves out of the land. The Israelites left in such a hurry, in fact, that the bread they baked as provisions for the way did not have time to rise. Six hundred thousand adult males, plus many more women and children, left Egypt on that day and began the trek to Mount Sinai and their birth as G‑d’s chosen people.
The holiday for the most part lasts 8 days and is broken up in 2 parts.
