So Benji climbs outside, slides down an awning and chases her taxi. Meanwhile, Dietrich pursues Benji in a sports car, but loses him. Alone again, Benji wanders to a hotel, where he spots Mary, Paul, and Cindy, but runs away when he sees Dietrich. Procuring a Doberman, Dietrich tracks Benji to the ruins.

Mary is reluctant to believe him, though. Meanwhile, the man pretending to be Dietrich takes Benji to a yacht, where Ronald and Elizabeth are waiting.
