Lawyer Dave Crabtree's troubles begin with the purchase of a decrepit 1928 Porter that claims through the radio to be his mother. Wife, Barbara doesn't want the old wreck but it has an overwhelming appeal for Captain Manzini, a very persistent antique car collector.

Dave fears for his mother's safety when car strippers are reported in the neighborhood.

Dave hears that Captain Manzini is dying but Mother warns him that Captain Manzini is up to something.

After being married for 8 years, Barbara and Dave decide to go on a honeymoon. However, Barbara's mother, an astrology nut, warns them of impending danger.

A collision with a truck leaves Mother with amnesia and Dave with a problem, how to bring back a car's memory.

Captain Manzini offers Dave one last chance to sell his antique car before using a molecular compressor to shrink it to the size of a small toy.

How can a car prevent a murder? That's what Mother has to figure out after she overhears three thugs plot the assassination of a visiting dignitary.

Mr. Kroot, the postman, know two thing about Dave. He saw Dave cementing the garage floor and also heard him say something about his mother not complaining anymore. So Kroot concludes that Dave has done his old lady in.

The future looks mighty bleak for Dave's mother when Barbara wins a new limousine in a supermarket drawing.

It's mutual love at first sight for Mother and wealthy Conrad Byron who offers to trade him limousine and chauffeur for Dave's car.

Dave returns from work too exhausted to think straight and he accidentally lets it slip that the car is really his mother.

Dave's mother allows the children to think that she like, Aladdin's lamp, can grant any wish.
