Hancock has been on holiday abroad and he tells Sid of his exploits in which he foiled an international gang of smugglers.

Hancock takes on a new job as an air steward. But one of the passengers on his first flight is Sid who is on the run from the police, and the other passengers include four police officers looking for a bank robber.

Hancock, a junior clerk in a City office for 19 years, receives a promotion when his army friends, who met at a reunion, place large orders with the firm. However, they are all fraudulent orders and Sid has the takings.
