The Chicago to Mackinac Island sailboat race has entered the final mile of their 333 mile journey, but they're in trouble. An overnight weather shift is causing high gusts and huge waves. More than 350 sailboats are trying to make it to the finish line in the Round Island Passage. The Coast Guard is on high alert, but Onyx's puppies, Search and Rescue, are rambunctious and creating a distraction on the response boat. The puppies are still in training and haven't learned to stay calm and lislten to commands like Onyx does. But when the crew needs assistance locating and rescuing the drifting sailor, Search and Rescue prove that they can truly live up to their names.
