The group of college students travel from Chicago to Egypt for spring break. Along the way, a book of ancient Egyptian maps is revealed to have writing within that glows in the dark.
Kayla attempts to make head or tails of the glowing book. Uncle Abasi and Aunt Rania regale the young students with stories of ancient Egypt and the Pyramid of Unas. Samira treats her guests to a fun night out clubbing in Cairo.
Samira comes up with a plan to steal her father's key and take the group into the Pyramid of Unas after midnight. They enter the Pyramid, and unbeknownst to them, the door shuts mysteriously behind them.
When Jordan commits an indiscretion, the group is suddenly visited by the terrifying spirit of the Pharaoh Unas. Incensed that his tomb has been defiled, he flies into a rage.
The floating, glowing eye of Horus leads the students down a passageway that leads to a deep cave lake. While crossing the lake on an ancient funerary boat, the group fights the evil serpent god, Apophis.
