In the guise of an appliance company saleswoman, Jeri leaves beautiful glass globes in banks as an introductory gift from her company. But the banks don't realize that the globes are filled with sleeping gas. When Papa Sam would play his violin and go into a passage so hi-pitched that it would shatter the glass globe, robbing the bank would be a simple matter with little risk. However, when they robbed a bank while Pancho was trying to cash a check, they soon discovered that Cisco Kid would be investigating and figure out their clever scheme.
