Half a mile from London's Heathrow airport, a wire enclosed compound holds visitors from Pakistan, India, Bangladesh, East Africa and Cyprus, who arrived without an immigration permit.

Amidst the confusion of Britain's immigration laws, an East End cockney, Reuben ('Mr. Fixit') Davis, operates a commercial Immigrants' Advice Service. While his methods of operation are, strictly speaking, within the law, his style is unorthodox and to some, highly offensive. Particularly so to the Minister of Immigration, who wants to put Davis out of business.

Undaunted, directly challenging the Home Office, Davis now plans a scheme to bring to England large numbers of stranded wives and children from the Indian sub-continent.

This film, in a broader sense, is about the whole experience of immigration control, and particularly about those immigrants who are confounded by Britain's diminishing relationship with its old Empire.
