Marineland, a popular water theme park on an island near Smallville, is hosting a number of Smallville teens including Lana Lang and Clark Kent. Nearby, Krypto howls to warn of an approaching hurricane as the park's public address system warns of the approaching hurricane for the teens present. As the teens run for the storm shelter, Clark deliberately dawdles and changes into Superboy.
Superboy and Krypto save a plane caught in the hurricane followed by rescuing a ship's crew whose vessel had gone aground on rocks. The two move on and help repair a dike that was in dire need of repair before moving on. Back at the shelter, Lana worries that Clark, who is not in the shelter, won't be able to survive the hurricane.
Superboy and Krypto spot a huge tidal wave heading for the shore and the two spin quickly to form small whirlwinds to suck up the wave completely and draw it away. With Marineland safe, Superboy and Krypto herd the hurricane away from land for good.
The teens leave the shelter and Clark is spotted in the water tank and says that is where he rode out the storm.
