Guido has lost it all. At rock bottom, and while wandering the shore, Guido spies a misshapen creature floating toward him in the water, riding on a huge chest. The creature offers Guido a path of revenge – switching bodies for three days in exchange for the untold riches in the chest. Guido unfortunately fails to see a potential down side.
