Four days earlier, Kellar and his military unit were attacking a Seventh Wave stronghold in the city of Veblensk. Kellar kills three high-ranking members of the cell but then disobeys orders by rushing inside a terrorist controlled building, where a hitman suddenly ambushes him. However, this hitman did not kill Kellar, who learns the man is an American, William Lennox, a former CIA wetwork operative. After faking his own death in Cairo, Lennox has become the leader of Seventh Wave.
