When Arthur Blenkinsop (Eric Sykes), foreman at Lillicrap Ltd., gives a job to the half-Irish, half-Pakistani Kevin O'Grady (Spike Milligan), the existing workforce don't take kindly to a new "wog" in their midst.

When all he wants to do is an honest day's work for an honest day's pay, Kevin has trouble understanding the work-shy and heavily union-based ethics of his colleagues.

Upon winning £250,000 in the football pools, Kevin suddenly finds that he has far more friends than he ever realized. His landlady cooks him a special meal, and the landlord stands a round of drinks at the local.

On his way to holy confession in case he gets killed at a football match, Kevin walks into the middle of a race riot and gets walloped and arrested. When Young Dick finds out that Kevin has doubled his chance of getting to heaven by being both Catholic and Muslim, he is ever so slightly appalled.

Among those giving O'Grady trouble is Kenny; he has always thought of himself as 'one of the lads', but since O'Grady's arrival, the black Cockney workman finds himself now firmly placed on the 'immigrant' side.

Redecorating the office for Cristmas, Smelly laments the impending lack of a Queen's Speech on the television that year. The Shop Steward is quick to denounce Christmas as a capitalist racket, but Kevin puts him straight.
