Armitage runs a chemical company that is on the verge of producing a gas that causes temporary disability. Clearly the military want it but it is also sought by a group of Japanese. Both Armitage and Madam Greenfly hire different people in the same detective agency to guard the gas and steal it respectively... confusion, double crosses and hilarity ensue...
