Gulley Jimson is a boorish aging artist recently released from prison. A swindler in search of his next art project, he hunkers down in the penthouse of would-be patrons the Beeders while they go on an extended vacation; he paints a mural on their wall, pawns their valuables and, along with the sculptor Abel, inadvertently smashes a large hole in their floor. Jimson's next project is an even larger wall in an abandoned church.
