With the Avengers vacationing on the sunny California beaches, Tigra hopes to finally conquer her fear of water, but things go sour when Iron Man challenges Luke Cage to a deep sea fishing contest and the two of them, ahem, bend the rules a bit. Iron Man sends a sonar pulse to stir up the really big fish, unfortunately rousing not only a monster from the deep, but also one seriously angry Prince of Atlantis...Namor, the Sub-Mariner! Lucky the Avengers brought the Hulk along! It's the slugfest to end all slugfests, and it does nothing to help Tigra's fear of water!
