Working as a clerk in a builder's office requires a quick brain and a pragmatic mind - something Norman lacks. However, he does possess a sense of duty. When his flatmate, Alec Potter, borrows a ladder without informing the boss, Norman tries to fix the situation but finds himself in a precarious position.

Norman and the boss's daughter should both be happy as he searches for a birthday gift for her. However, Alec plays a trick, leaving Norman in a risky situation.

Norman is not the person you want around when the company transitions to double glazing.

For Norman, the solution to sharing a room with Alec is clear - partition. When Albert, the boss, discovers the decrease in timber stocks at the builders' yard, Norman is immediately suspected. Determined to prove his innocence, Norman sets out to catch the real culprit.

Alec's artfulness cannot even separate his new girlfriend from her chaperone.

Norman's curiosity about Alec's well-being leads to unexpected consequences.

With the boss sick with flu, Norman acquires a liking for leadership.
