The CyberSquad is on an island and needs to visit Dr. Marbles. The group members have a map but don't know where they are on the island, so they head to the shore.

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.
