Examinies the trade in monkeys for scientific purposes. The demand for monkeys cannot be met by breeding in captivity so many monkeys are trapped in the wild to be shipped back to the West to laboratories. Looks at the conditions and treatment of a supplier 'Shamrock Farm' in the south-east of England. Includes interviews with Dr. Judith Hampson, a research consultant with the RSPCA; Terry Hill, an investigator for the abolition of vivisection; and Jim Cronin a primatologist.
