After several foreign amateur athletes defect to the United States, Steve goes undercover as an American amateur boxing champ to infiltrate a suspected assassination team made up of the alien expatriates. While training for the bout, Steve notices that four of the foreign boxers can lift and move more than four thousand pounds together. And, using OSI computers, he and Oscar Goldman are able to pinpoint the foreigners' assassination target, but not before Steve is drugged and nearly killed.
