Rocky is a lobster boat that is smaller than most of the other lobster boats. His crew boards him every morning, and they go out lobstering together, and Rocky couldn't be happier. But while Rocky is content, sometimes the bigger boats make fun of him, and he wonders what he can do to prove himself.

The answer comes with a terrible ocean storm one night. The big dragger Quest is broken free from his mooring by the wind, and the only one who can save him is little Rocky. Steeling his nerves and throttling full speed ahead, Rocky plunges into the stormy waves to save a new friend and show he's just as capable as everyone else.
