"Fingers" is a magician—a really, really good one. When his unfortunate kleptomania sends him to jail, he meets the Daltons and soon escapes with them. After Lucky Luke puts everyone back behind bars, he takes pity on Fingers' unfortunate tendencies and agrees to try to rehabilitate him. A daunting, frustrating task, for confusing and complicating matters is second nature to a magician. Riding off into the sunset is going to be a difficult trick this time!
