Gidon Aronson, an American who has served in the Israeli military, has made a promise - to check up on Noa, a Mossad officer's niece, a college student in Baltimore. The uncle is concerned about Noa's welfare, given rampant anti-Israel sentiment on many college campuses.

What begins as a simple favor, develops into a murder investigation when Noa's room is vandalized and two young men are subsequently killed. Gidon and the police uncover a foreign intelligence cell that always seems one step ahead of them. When Noa is forced to leave town, Gidon returns to the Middle East and undertakes a personal undercover operation so risky it may cost him his life.
