Lana has a premonition about an Industrian attack on High Harbor, a message she is sure was sent by her grandfather. To ease her mind, Conan takes her to Tito's village, where Jimsy has become a pig herder, and he also shows her the treehouse they have erected to live in. Meanwhile, Orlo is visited by Dyce, who has tired of life on land and wants to set out to sea again. Dyce convinces Orlo to help fix the Barracuda, in return for Dyce helping to kill Conan and Jimsy. But at the very moment the deed is to be committed, Industrian troops under Monsley launch an attack against High Harbor.
