The Defenders accompany Lothar to his hometown in Jamaica, where the new children?s wing of a hospital will be dedicated in his honor. While there, Dr. Barbeau informs then that a new wonder drug is doing fantastic things for the children, but is difficult to obtain because a mythical sea serpent has been stealing it. A cult, led by Papa Duke, worships the serpent, and L.J.?s new friend, Felice, tells him that her brother has joined. While spying on a ceremony L.J. is captured and Felice escapes, but not before learning that Papa Duke plans to lead the youth of the town on a campaign to seize power from their elders. L.J. is forced to drink the breath of the serpent, which gives him super-human strength and hypnotizes him into following Papa Duke. L.J. kidnaps Kshin for a sacrifice while Rick and Jedds search the water submarine for the monster. The Defenders invade the cult and rally the town citizens to control the kids. L.J. becomes his old self when the drug wears off, Kshin is rescued and Papa Duke turns out to actually be Dr. Barbeau! Barbeau has been operating a mechanical sea serpent and stealing the drug.
