Morgan and her dog head out on an accidental journey down the river that flows past the summer cottage where they holiday with Morgan's mother. As they float along the river they observe landscape and life on the water, various birds and people enjoying the activities the river has to offer. But the story is not only about their adventure, it is also about community, about how all the people who see them drifting past hurry off to make sure that they come to no danger. The story ends at the local wharf where the entire community comes together to celebrate their adventure and their safe return.
