After Haven’s incredible discovery of how to communicate with dolphins, she learns that they’re usually thinking about food and fun! She plays the dolphins and humpbacks near her underwater lab some Beethoven music, as a way of introducing them to human entertainment. Haven and the dolphins get so absorbed in their newfound ability to interact that they don’t notice that all the music and commotion has attracted a couple of curious great white sharks! Once the sharks arrive, the dolphins panic, knocking over Haven’s communications antenna! Worse, a humpback whale gets crowded into the cliff of a nearby island, causing an underwater avalanche! The rubble falls onto the living quarters module of the lab, crushing it! Haven is in mortal danger!
