Veronica and Summerlee are out gathering fruit and floral specimens when they are attacked by a huge bee, one the size of a man. Summerlee is stung, and it leaves him near death. The only cure is the nectar in the heart of the hive. Veronica, Malone and Roxton travel to the hive, leaving Challenger and Marguerite behind at the treehouse to care for Summerlee. Summerlee is delirious with fever, and imagines Marguerite is his long-dead wife. She plays along, to sooth him. In the meantime, Veronica, Malone and Roxton do make it to the hive, work their way deep into it, gather nectar, and head back quickly to the treehouse, just in time to save Summerlee's life.
