Three friends, Alf, Bill and Fred (a man, a dog and a duck), share the same passion for bouncing up and down. One day Bill, the man, inherits a large sum of money and gives up his friends, who go on bouncing without him. But money does not make happiness and Bill, having fallen into depression, jumps off a 7 story building. He survives but loses his memory. After being welcomed back by his friends, the threesome decide to open the Dog and Duck agency, a business selling happiness to people.
