[3] George is a disaster-prone zoo attendant who accidentally discovers a substance that accelerates motion, enabling his greyhound to run faster.

This attracts the interest of a gang of criminals, led by Doctor Sundermann (a foreigner), who have their base in a "haunted house" next to the zoo.

George's housekeeper, Mrs McAllister, has a daughter, Jean, who romances vet Jimmy Alderson - but who is also loved by Ted Inchape.

As with all Cinesound comedies in the late 30s, uncredited work on the script was performed by Hall, Jim Bancks and Bill Maloney.

[5] The story followed a formula developed in Wallace's Ticket in Tatts: "George is given a simple labourer's job... Quite innocently is fired...

Wallace's female co-star was Lois Green, an actor with extensive stage experience with J. C. Williamson Ltd, who left Australia after filming to go work in London.

[7][8] The romantic male lead was an unknown amateur actor called John Fleeting, who later appeared for Hall in Come Up Smiling (1939).

[9] The cast also included John Dobbie, Wallace's long-time stooge on stage, and Howard Craven, a former publicity writer for MGM in Sydney who had gone into acting.

They cut out a lot of good comedy, to suit their own ends; to get it to second feature length and to pinch the title.
