Inept bank manager Peter Duffley believes his assistant has fallen in love with him.

Iris has won 250 pounds on the National Lottery—or so she thinks. Unfortunately, absent-minded Peter has forgotten to buy the tickets.

The staff organizes a collection for the cleaner and also goes on a fitness drive.

Unless he can land a major account very quickly, Peter looks set to miss out on his bonus again.

When an ordinary day at Albridge C&P Bank is rudely interrupted by two apparent bank robbers, Peter heroically protects his staff (in his version of events).

Both Peter and assistant manager Susan apply for a managerial position at another branch. Peter steals Susan's proposal, but gets locked in the bank over bank holiday.
