An ancient code. A deadly killer. A truth buried beneath the sands of time.

FBI Special Agent Charlie Reed thought the Surgeon - a notorious serial killer - was a ghost from the past. But when a new series of murders erupts, each marked with strange, arcane symbols, the trail leads Reed across continents to Egypt... and to a chilling revelation: the Surgeon has returned, and this time, his killings follow a pattern—one tied to a purpose more terrifying than anyone imagined.

Meanwhile, in Egypt, Alex MacLure has uncovered more encoded messages in ancient tablets, this time referring to a forgotten symbol. MacLure's name appears in a programme written by a brilliant AI student. The student reaches out with a wild theory - but before MacLure discovers the truth, he’s arrested for a murder he didn’t commit.

Thrown together by fate and hunted by forces beyond their understanding, Reed and MacLure must unlock an ancient secret. They must stop the Surgeon before he unleashes a plan, millennia in the making.
