In one of his rare performances without Bud Abbott, Lou Costello plays a delivery boy who invents a machine which turns his girlfriend into a giantess.

This black comedy opens with Louisa Foster donating a multimillion dollar check to the IRS. The tax department thinks she’s crazy and sends her to a psychiatrist. She then discusses her four marriages, in which all of her husbands became incredibly rich and died prematurely because of their drive to be rich.
