As a security guard at the bank, one of Preston's responsibilities is help to lock the main safe at night. He uses a stick on touch-sensitive vault floor to check that alarm works, before locking the safe for the night.
Latter that night, Joe and Preston are in the Security office, when suddenly the alarm goes off. Preston checks the security camera, and finds a hole has been cut into the vault and the gold bars are missing!
They both dash next door to Harman's Department Store, to discover the thieves have escaped. Toy Packer Tanner has seen nothing so they guess they must be in the container. Joe makes a phone call to stop the rocket from tacking off, but its too late the rocket is on its way to the Coralville Children's Hospital.
