Jackie, Matt, and Inez brainstorm how to build a ramp to get up the steep cliff to the island. They create a design for the ramp such that it can be easily transported and will serve the purpose of getting them to the island.
To escape the island, the CyberSquad must reach before sunset one of the portals that Motherboard has placed on the island at random. The group uses the map to determine the distance to each portal and accounts for facts such as steep climbs and bridges being down. The kids and Digit decide to take the rapids to the bay, where they successfully reach the portal.
