 Amos Perry is a lonely sailor who wants to sail around the world with his only companion, an old mutt with whom he shares his boat. The dog, however, is rabid, and runs off as soon as he docks in Danger Bay. After a run in with the dog, Nicole is bitten while trying to collect marine samples near the docks. Soon thereafter, the harbor patrol orders Amos to shove off since he doesn t have a docking permit. He tries to find the dog first, though, and is also bitten. Grant and George then try to get the antidote sent to Vancouver by plane for both Nicole and Amos Perry. After some sleepless work burning the midnight oil, George secures the antidote, which is delivered in time. Dr. Chen presents Amos with a new dog, whom he names Ralphie. Amos sails off to finish his around the world trek, waving to the Danger Bay crowd on Grant s porch as the credits roll.
