Our sister ship is lost and we are launched into the ocean on a search mission. Sammy the Dolphin will guide our mini-submarine and protect us from dangers. And of course, we will need his protection. We soon encounter a sea monster and have to run for our lives. We dart inside an old tanker ship, pursued by the monster; we escape but the monster bites the tail off of our submarine, hitting the fuel tank. The captain hits the ejector button; the explosion blows us out of the water and we splash down back at the mother ship with our mission completed.
