Walter Black's mood is as dark as his last name. His job is failing, his wife has had enough, and his son hates him! Deep in the depression - and in the middle of a suicidal state of mind - Walter finds a dirty hand puppet in a rubbish bin. A beaver. With the fur animal on hand can once again speak directly from the liver. And on top of that with a British accent! But as Walter regains his composure, his new beaver personality soon takes over.
